R35 GT-R 90mm Catted Midpipe

The AMS Performance R35 GT-R 90mm Catted Midpipe is engineered to significantly enhance exhaust flow, making it one of the largest midpipes on the market. Its design utilizes a substantial 90mm (3.5") primary pipe, which is larger than typical dual 76mm (3") merging systems, to reduce turbulence and back pressure. This optimization directly leads to improved turbo response and increased horsepower, providing a noticeable performance upgrade for your GT-R. Equipped with high-flow GESI Ultra High Output (UHO) catalytic converters, this midpipe meets emissions regulations for 49 states. These EPA-certified converters offer exceptional emissions control without compromising performance, delivering power comparable to a catless midpipe. The catalytic converters are designed for durability, capable of withstanding temperatures up to 1500°F and heavy driving conditions, making them suitable for both street and track use. Constructed from premium 100% 304 stainless steel with a .049" wall thickness, this midpipe features precision TIG welding by AMS master fabricators. It includes twin 76mm (3") stainless steel flex sections and robust 3/8" thick stainless steel flanges for secure connections, eliminating issues with band clamps or slip fits. The package includes necessary gaskets and hardware for installation. This midpipe is specifically designed for the 2009+ Nissan R35 GT-R models with the VR38DETT engine. Please be aware that this product is not available for purchase for emissions-controlled vehicles located within the state of California or for shipping to California addresses without a completed AMS Race Waiver form. International users should comply with their local laws and regulations.
