The AMS Nissan GT-R 90mm Race Exhaust is one of the most free-flowing performance-based exhausts on the market. Through our many years of experience in the design of aftermarket turbo exhaust systems, we noted that a higher level of performance could be achieved with improved routing and increased tube diameter over the existing stock GT-R exhaust design. While the stock and many other popular exhaust systems on the market feature intricate bends that would impede upon efficient exhaust flow, AMS decided to develop a system that would incorporate mild bends and deliver exhaust gases from midpipe to tip in the most direct way possible without sacrificing fitment. This, coupled with a large 90mm primary pipe that gently flares into two 76mm secondary pipes made it possible to further reduce undesired backpressure and turbulence. To cap it off, four polished OEM-style tips were chosen to continue our overall goal in the AMS GT-R engineering project – which was to retain as much OEM-styling as possible in order to build some extremely potent stock-appearing GT-RS.
This race exhaust is a two-piece system constructed of 100% stainless steel with all seams and flanges professionally hand TIG-welded in-house at AMS. For added durability, a 3/8 thick flange was incorporated into the design for a clean and secure seal to any stock, AMS brand or other brand midpipe featuring stock mounting dimensions and features. In addition, a v-band clamping system at the mid-section ensures an extremely solid seal without the use of a gasket and allows for minor rotational adjustments to ensure excellent fitment.
