The AMS Nissan GT-R 90mm Cast Downpipes are the largest, most free-flowing available on the market. During testing our shop GT-R with AMS upgraded turbos saw gains in the power band of 100 wheel horsepower and over 130 ft lbs of torque with this simple bolt-on! Turbo spool-up was also improved by almost 400rpm!


Designed by our engineering team using Solidworks (3D CAD software) the inlet and outlets were designed to optimize exhaust flow. Most other systems implement 76mm (3”) downpipes that can cause unnecessary backpressure. By using a larger 90mm (3.5”) primary pipe we were able to optimize exhaust gas flow, freeing up horsepower and improving spool time.


In addition our downpipes feature stainless steel cast construction allowing for improved exhaust flow and OEM like reliability, an attribute previously unattainable with the competitors sheet-metal, handmade units. With unrivaled fit, finish and performance the AMS Nissan GT-R 90mm cast Downpipes will easily support any future items are SOLD AS IS and ARE NOT eligible for returns or exchanges.
