The ETS GT-R 4.0" Stainless Steel Exhaust System is one of the largest and highest flowing exhaust systems on the market! The key to making horsepower in a turbocharger vehicle is by eliminating back pressure and we do this by using a full 4.0" exhaust system without any compromises.
One of the many key features of our exhaust system is a true 4.0" merge collector. This is important because around the 1200whp range most exhaust systems will start to become restrictive. We've tested our system at over 1700whp without any performance losses over an open downpipe.
