This is the exhaust we designed for our V8 conversions. It's a true dual exhaust setup that uses a custom-made muffler that is effectively a pair of mufflers with an internal crossover pipe. It includes two high-flow catalytic converters that will keep OBD-II systems and emissions testers happy without a cost in output.
This kit does not include headers.
As with all of our exhaust systems, this is bent out of stainless steel using a CNC bender for minimal welds and maximum accuracy. The entire system is made of stainless steel and carries a lifetime warranty. The cats have a 5 year/50,000 mile warranty on the shell and a 25,000 mile warranty on their emissions ability. Please note that we cannot ship this product to California as the cats are not CARB approved.
Available for NA, NB using the V8Roadster subframes and built to clear the CTS-V Getrag diff. Also available for the NC using the Camaro AAM diff. They may clear other applications as well, but that's for you to work out. We also have an ND version that is listed separately. Our NC variant is not currently available.
