They cause you to lose power, and likely part of the reason you’re buying a high-end car like a Mercedes is the power that comes with it. Since the production of the first diesel truck in 1924, and the first diesel car in 1936, Bosch has been one of the world’s leading providers of diesel technology. The exhaust-gas treatment and dosing system, Denoxtronic, is being used in a larger number of diesel vehicles than ever before. Therefore, it is growing in importance, and thus, potential for the workshop. Adding power to a diesel simply means adding more fuel and more air. In stock configuration, let's say my powerstroke injects fuel from 1 unit at idle up to 10 units at full accelerator.
Additionally, an upgraded downpipe can improve the exhaust flow, which can result in a smoother and more efficient engine. It can also reduce turbo lag, which is the delay between pressing the accelerator and the turbocharger spooling up. If you’re looking for the performance gains of a decat but still want to remain legal for road use, there are a few options to consider. One option is to look for high-flow catalytic converters (also called sports cats) that offer improved performance while still maintaining emissions compliance.
Effectively increasing low end torque and maximizing power throughout the entire RPM band. Your overall exhaust volume will increase but keeping the interior noise resonance under cruising speeds at a reasonable level. Built as a direct OEM replacement, lower downpipes are designed to be an addition to your cat back exhaust system. We maximize performance by replacing the OEM lower catalytic converters and increasing the tubing diameter. The biggest potential issue with upgrading any part of your vehicle’s exhaust system is failing emissions tests.
Maybe he knows something about the 7.3L fueling curve or something that I'm not thinking of. As to the referenced article, they cheated on the HP number by spraying a bit of laughing gas. Plus Cummins are awesome MPG makers since they don't have 2 extra cylinders worth of pistons, rods, rings, and weight being dragged around the crankshaft.... You need a small town old operator with a pipe bender that can copy the curves of the old pipe. Got me a new "donut gasket" to seal it up and an extra hanger.

Following the restrictive downpipe section, the stock unit subjects the exhaust gases to the choking effects of the catalytic converter. After the cat, it flattens out into a section dubbed the infamous "U-Bend," which is a section of pipe crushed into a "U" shape by GM in order to fit a rear o2 sensor. This section has less volume than the same length of 2" pipe, and approaches the volume of a 1.75" pipe with the rear o2 sensor in place! Gains of over 15HP have been seen, along with a substantial drop in knock. Most users can drop a pulley size and/or eliminate 5-7 degrees of knock. Lastly, for the best results and to avoid any potential issues, it’s recommended to have a qualified mechanic perform the installation.
Test pipes do not have the honeycomb insides of catalytic converters; they are just hollow pipes, so they eliminate back pressure even faster. Secondly, to fully capitalize on the power gains from decats, you may need to remap your car’s ECU. Custom tuning ensures that your engine runs optimally with the increased exhaust flow, maximizing the performance benefits.

The metals act as a catalyst and react with the emissions and shift harmful exhaust fumes to less dangerous pollutants. The contents inside need to be incredibly hot for the conversion to work efficiently, which is why ceramic is used. Ceramic metal heats fast and stays very hot for a long time. Without the catalytic converters, gases like nitrogen oxide, carbon monoxide and other hydrocarbons are quickly emitted into the atmosphere, causing harmful environmental air pollution. Downpipes are meant to meet emissions standards and provide enough air movement for a stock vehicle’s performance requirements.
Ultimately, understanding the trade-offs and making an informed decision will help you make the most of your automotive customization journey while keeping the downsides of downpipes in check. While many car enthusiasts turn to downpipes to boost performance, it’s important to understand that the effects may not always be positive. Let’s explore how downpipes can impact your vehicle’s overall performance. Essentially, downpipes are for turbos only, while the similarly-tasked header is for non-turbocharged vehicles. Technically you can still use headers with a turbo, but it would have to be a custom turbo system that connects to the turbos in the exhaust after installing the header base.
It's a vital component in moving the exhaust gases through the system as efficiently as possible. You'll be able to outperform your competition on track day, while upgrading your exhaust note as well. Stainless steel downpipe replaces stock turbo outlet pipe with catalytic converter and signigicatly reduces exhaust restrictions.
This not only indicates potential problems but can also affect the vehicle’s performance. So we know from the above that an automotive downpipe is an effective solution to control emissions by reducing the temperature in exhaust gas. To do that, the downpipe’s cat needs to filter gases into a large area.
Also, removing the DPF could have a negative impact on performance, engine life and long-term reliability. Consequently, you would only make a further useless extra expense, paying for a product that is NOT approved in any case.

With its position immediately after the turbo, the efficiency of a downpipe directly impacts the turbocharger’s spool and performance. Constructed from robust materials such as stainless steel, downpipes like the mk7 gti downpipe and 2.0 tfsi downpipe are designed to withstand high temperatures and corrosive exhaust gases. The design often includes a small radius of curvature, ensuring good maneuverability and low-pressure drops, which is essential for optimal engine performance. Additionally, upgrading to a larger downpipe can cause the turbocharger to spool up faster, resulting in increased boost pressure. This increased boost pressure can cause the engine to run lean, which can lead to engine damage. To prevent this, a professional tuner can adjust the ECU to ensure the engine runs at the optimal air-to-fuel ratio and boost pressure.
To truly harness the benefits of an aftermarket downpipe, a vehicle’s engine management system usually requires recalibration. This involves adjusting the ECU to accommodate the changes in exhaust flow and backpressure. Failing to tune the engine after installing a downpipe can result in poor performance, decreased fuel efficiency, and even potential engine damage. However, there are several potential drawbacks that should be considered before opting for a downpipe installation.

I may have these numbers wrong, but I'm pretty sure my powerstroke has a base injection timing of 13 BTDC. Many of the more aggressive tunes put that number closer to 27 BTDC. The benefit is that the fuel has more time to exert its pressure on the piston, and there is more time to inject fuel. The reason OEMs don't do it is because it makes a lot more vibes and noise, and it also spikes NOx emissions way beyond what the EPA would allow. Chevy put out some 454 cubic inch engines that only made 215 hp and only got 10 mpg.
Stock downpipes have catalytic converters, but aftermarket downpipes are available in catted or catless forms. Because it is directly connected to the exhaust side of an engine’s turbos, an aftermarket downpipe can significantly relieve an engine of back pressure. Installing aftermarket performance downpipes and decats can greatly enhance the performance of a vehicle.
The most obvious disadvantage is the environmental impact of unrestricted exhaust flow. It’s important to keep in mind, downpipe upgrades will prevent you from passing emissions tests and may not be legal in all areas. This package is viewed as "stage 2" on the upgrade paths of many Volkswagen/Audi vehicles.
So, to all the performance enthusiasts out there, if you’re seeking a way to unlock your car’s true potential, consider upgrading to decats or catless downpipes. The horsepower gains, improved exhaust note, and overall thrill they bring to your driving experience are unmatched. Overall, downpipes offer numerous benefits that make them popular among car enthusiasts. By improving engine performance, enhancing the exhaust note, and improving fuel economy, upgrading the downpipe can provide a significant boost to any car enthusiast's vehicle.
Decats and catless downpipes are a modification that falls into a legal gray area. When upgrading to a performance downpipe, the increased exhaust flow can cause a lean condition in the engine, where the air-to-fuel ratio is not optimal. This can lead to engine damage, reduced performance, and increased emissions. To prevent this, it may be necessary to remap or tune the ECU to adjust the air-to-fuel ratio and ensure the engine operates optimally. An aftermarket downpipe is an essential component when it comes to getting the most power possible from your stock turbo. With a free-flow exhaust system, you can expect higher levels of performance!

Exhaust or turbo downpipes play a crucial role in your vehicle’s exhaust system. They are the connecting pipes that channel the exhaust gases from the turbocharger to the rest of the exhaust system. Downpipes are usually located close to the engine and serve as a bridge between the turbo and the catalytic converter.
When your turbo spools off idle, any claim of backpressure affecting torques is nullified. I would expect that a larger less restrictive exhaust would help the turbo spin up lower in the rev range, which should theoretically help with the torque, not adversely influence it. Not having a lot of success with the muffler shops - don't seem to be able to get a good fit. Truck has been restored and it would be nice to have good fitting pipes so there won't be leaks.

Another reason downpipes are popular is that they can enhance the sound of the car's exhaust. Upgrading the downpipe can give the car a deeper and more aggressive tone, which is especially desirable for car enthusiasts.
While downpipes can undoubtedly offer performance benefits for those seeking more power and an enhanced engine sound, it’s important to weigh these advantages against the potential drawbacks. Emissions concerns, warranty implications, and the need for recalibration are just a few of the cons to consider. Furthermore, the impact on turbocharged engines and overall drivability can’t be overlooked.
The straight exhaust pipe needs to be changed every 80,000 km and the tailpipe every 100,000 km (average estimates). The x pipe and like all the parts of the automotive system is exposed to rust, cracks, and punctures. Overconsumption of fuel, unwanted noises, or the smell of gasoline can all be symptoms of a faulty exhaust downpipe. In practice, the difference in power gains between a catted and cat-less downpipe is negligible.
When it comes to automotive enthusiasts looking to boost their car’s performance, the installation of aftermarket modifications is a common practice. One such modification that often sparks debates is the downpipe. A downpipe is a crucial component of an exhaust system that connects the exhaust manifold to the catalytic converter. It plays a pivotal role in directing exhaust gases away from the engine and enhancing overall performance. If you crave that deep, throaty growl and ear-tingling rumble from your exhaust, decats are your ticket to automotive symphony. Catless downpipes remove the catalytic converter, allowing the exhaust gases to flow more freely and creating a more aggressive and attention-grabbing exhaust note.

Some packages shipped from the manufacturer may or may not require signatures for package release. An O2 spacer moves the sensor out of the direct flow of the exhaust, tricking the ECU into seeing the emissions numbers it is looking for. O2 sensor spacers are not a guaranteed fix for a check engine light, and will not always work. A wider downpipe diameter always increases flow rate and therefore boosts performance and response. The preferred material for downpipes is stainless steel, as it easily withstands high thermal stress. Regular maintenance of the downpipe exhaust downpipes system is essential.
Remember to invest in quality components made from durable materials like stainless steel or titanium. These materials can withstand the extreme temperatures and harsh conditions encountered in high-performance applications. Before jumping on the decat bandwagon, there are a few factors to consider. Firstly, there are legal implications to removing the catalytic converter, depending on your location. Going catless may violate emissions regulations, so it’s crucial to check local laws and regulations before making any modifications. Any other use, including recreational off-road use, may be in violation of local, state, and Federal laws.
These components deliver the same result, despite not originating from the car's manufacturer. If you obtain these as direct replacements, they do not void your vehicle's warranty, but it's essential to make sure you're purchasing from a reputable supplier – like us. In fact, some aftermarket alternatives are better – or at least equal to – authentic products. But like all things in life, if the price seems too good to be true, it probably is. Located on the NSW Central Coast, Pro Speed Racing is a retailer, wholesaler and importer of premium automotive parts.
It has no filtration function but is responsible for making the junction between the elements of the line. They filter pollutants out of the exhaust gases, and depending on their design and material, can also help reduce exhaust gas accumulation. If you’re itching to know more, check out the information on our sport cats. We are currently offering $75 to $100 (depending on year) in store credit to purchase your stock catalytic converter back from you. If you're interested, take a photo of your stock downpipe and email it to We will provide prepaid shipping labels for domestic (U.S.) shipments. Leaders in aftermarket & carbon composite parts development for a variety of vehicles.
By upgrading the stock downpipe with a high-performance one, you can increase horsepower, improve exhaust flow, and reduce turbo lag. Unfortunately, the factory downpipe that comes as standard equipment in your car was designed for anything but performance. The factory downpipe severely restricts exhaust flow and therefor has adverse effects on horsepower, especially once your car is "chipped".
There are daily-driver diesel trucks putting down 1200 hp and 2100 lb-ft of torque. I've seen trucks pull into a dyno day with a travel trailer, unhitch, turn a knob on the dash (literally) and lay down 1000+ hp on the dyno at the rear wheels. Then they turn the knob back down, hitch up, and drive home. If you did the reliability calculations alone on the bearings it will probably die in under 100K so that isn't good for a diesel. I asked the "expert" for clarification on the other forum and he hasn't written back yet, but I have come to respect his tech on other subjects.
