Description The Alpha R35 GT-R 90mm Race Midpipe is one of the largest midpipes available on the market. Where most systems implement two 76mm (3?) pipes that merge into a single 76mm (3?) primary pipe, we offer a larger 90mm (3.5?) primary pipe to optimize exhaust gas flow. This reduces turbulence and unwanted back pressure – freeing up horsepower and improving turbo response. ALPHA GT-R 90mm Midpipe with Race Cats 90mm Exit. 2009 and up Nissan GT-R, Fits all USDM Models, European and JDM models.
