AMS Alpha Performance R35 GTR 102mm Titanium Exhaust (Not for Street Use) KYB EXEDY stock replacement lightweight flywheelThe AMS Alpha Performance 102mm Titanium Exhaust for the R35 GTR is one of the largest units available on the market because it combines the mid pipe (Y pipe) with the rear exhaust section for a much larger than standard system. Where most systems implement 90mm pipes, the Alpha exhaust offers a larger 102mm primary pipe to optimize exhaust gas flow. This reduces turbulence and unwanted back pressure freeing up horsepower and improving turbo response.
