The Alpha R35 GT-R 90mm Catted 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.
Remain Compliant With No Loss Of Horsepower
So that your R35 GT-R remains compliant with state and local emissions regulations, our midpipe incorporates a set of high flow catalytic converters that are EPA certified in 49 states. These GESI Ultra High Output (UHO) stainless steel cats provide the highest level of emissions control with no notable loss in horsepower when compared to a cat-less midpipe.
With an Alpha 90mm Catted Midpipe installed, your GT-R will maintain the power of a straight pipe setup without the hassle of having to switch back to your stock midpipe in the event you are called for emissions testing. Our cats are designed with racing in mind and can handle the most severe of driving conditions. Unlike standard cores used by many of our competitors, these will withstand up to 1500 degrees F and will not rattle loose after repeated heat cycles and heavy driving.
Superior Construction. No Compromises
Like all products we manufacture, the Alpha R35 GT-R 90mm Catted Midpipe offers you unrivaled fit, finish and performance. Each piece is constructed of high quality stainless steel and hand TIG welded by one of our AMS master fabricators. In addition to a superior set of catalytic converters, we also use the highest quality stainless steel flex sections and 3/8” thick connecting flanges to complete an overall design that will last the lifetime of your GT-R.
