Restrictions in the exhaust system robs horsepower and torque especially on turbocharged cars.  Thus, removing as much exhaust flow restrictions will increase horsepower and torque significantly.  The factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction.  The factory catalytic converter is made up of catalyst material formed into "honeycomb" weaves.  Exhaust gas must pass through these tiny "honeycomb" weaves on their way to the exhaust system thus causing a major exhaust flow restriction.  It also causes turbulence after the catalytic converter which causes the exhaust flow to slow down (which increases restriction).  By replacing the factory downpipe/catalytic converter with our Competition Series Downpipe, more power is unleashed!  You will feel the difference instantly. 

Our Competition Series Downpipes is constructed out of 100% 304 grade stainless steel and utilize mandrel bent piping. They are 100% TIG welded by our in-house fabricators and built in the USA.  Factory Style flanges are CNC machined cut out of billet 304 stainless steel.  Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods.  The O2 sensor is positioned at the factory location.  100% bolt on. 

Our downpipes are designed to fit perfectly with either the factory exhaust system or your aftermarket exhaust system.  There are no compatibility issues whatsoever.  The downpipes will come by default with brushed finish.

The S68 engine has 2 primary catalytic converters and 2 secondary catalytic converters for a total of 4 catalytic converters.  Our Competition Series Secondary Downpipes replace just the secondary section You can retain the factory primary catalytic converter or aftermarket primary section.  Will match up to factory or aftermarket exhaust systems.  The secondary downpipes are after the secondary o2 sensor that monitors the catalytic converter so changing it will not set off a check engine light (CEL).

Ceramic Thermal Coating - The purpose of ceramic coating downpipes is to keep heat from the exhaust gases inside the downpipe from radiating out. This keeps underhood temperatures lower and less heat absorption by nearby parts/surfaces.  Another added benefit is that by keeping in heat (energy) in the exhaust gases inside the downpipe, exhaust flow velocities stay up, resulting in lower backpressure. The ceramic coating also adds additional corrosion resistance. We utilize the best ceramic coating possible. Our thermal coating can resist up to 2000F of heat. It is available in black only (all the other colors cannot withstand the high levels of heat).

Reduce sound vibrations in your car! Works great! This is not sound proofing, it is Sound Deadening
Size: 10 sqft, Size: 10 sqft
This Butyl rubber sound proofing kit includes nine 15 1/2" x 10" peel and stick panels. It really is a lot of coverage, but I still will need a second box to finish my car doors. The instructions are easy to follow and the only tools you need are scissors or a knife and a small roller, but you could get away with using a pan scraper to press the product down. You may need paper and a pen to make a template for certain areas, though. I used some cardboard from my recycle bin to cut template pieces for the hard to see areas inside my doors. This is fairly easy to install once you have it cut into pieces, just peel the backing off and stick it on. Be very careful to not let it stick to itself, as it will be nearly impossible to separate. This stuff is crazy sticky! No worries about it coming off once you've stuck it to your car. To add this to your car doors, you will have to remove the interior door panels, but there are lots of YouTube videos on how to do this on all sorts of cars. Note that is is sound deadening material - Not sound proofing! You do not need to cover 100% of the car with this. The material is designed to stop noise from resonating through metals, so even one piece of this on a large area of sheet metal will stop the sound vibrations quite a bit. I am covering about 80% of my car doors with it, then planning to put sound proofing on top of it. This sound deadening material needs to come in contact with the metal surfaces to stop the sound vibrations, so it would not be very helpful to put it on top of sound proofing material. Also note that the installation requires temperatures above 50° Fahrenheit. Since it is winter, I've warmed up my garage while working on this project. In low temps, the sticky stuff would probably have trouble adhering to cold metals. So far I have tested just having it on my front doors, but I already can hear the difference. This soundproofing definitely does minimize road noise and external sounds from getting inside your car. It also stops music vibrations, so my radio now sounds clearer than it did before. I don't plan to pull out my vehicle carpet to install on the floor, but I would imagine that if I did it would greatly reduce the road noise even more. Definitely five stars on this product!
