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 Catless Downpipe, more power is unleashed! You will feel the difference instantly. 

Our Competition Series Catless 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. The factory turbocharger turbine housing utilizes a 3.5" V-Band flange which we have duplicated and 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. The factory donut flange design is retained.  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.

OPTIONS

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).

Great Divider
Comes assembled. It is heavy, but fairly easy to move and use. I’m 5’4, 110 and I can do it myself. It’s thick, it’s tall, it looks good, not sloppy or cheap. Doesn’t smell. Great room divider. We use it for our office between our desks.

Good purchase
Color: White, Size: 8 Panel
I bought this in white for use in a finished basement to hide equipment on the wall and create a nice space to place a bed. Because it doesn’t need to be moved and the room is temperature controlled, I expect it to last for a long time. The screen is pretty and I like that the woven material is not easily breakable. I’m pleased with the purchase.

Perfect & light weight divider
Color: Charcoal Gray, Size: 8 Panel
I really like this divider. I have it in my bedroom which is also where my "work from home office" is. The divider blocks my bedroom and dresser perfectly. It's very light weight and very easy to move.
