Alpha R35 GT-R “Widemouth” Downpipe Upgrade
Unsurpassed Performance, Durability and Sound
The Alpha Nissan GT-R 90mm Cast Widemouth Downpipes are the best performing and most durable on the market. During testing our shop GT-R with Alpha upgraded turbos saw gains across 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!
Unparalleled Durability and Performance through Proper Engineering
Our downpipes perform better and are not prone to cracking like the alternatives offered by the competition. Their versions have many welded seams which are prone to failure.
By casting these downpipes in robust 304 Stainless Steel we were not limited by the design restraints of hand fabricated construction. The AMS engineering team utilized Solidworks (3D CAD software) to blueprint the inlet and outlets with smoother features and geometry to optimize exhaust flow. They also provided thick flanges to prevent exhaust leaks and utilize the factory mounting hardware for OEM like fitment.
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 while improving spool time and throttle response.
An exhaust note that is music to your ears
AMS Widemouth Downpipes offer a more pronounced, throaty exhaust note under wide open throttle yet are subdued at idle and while cruising. A perfectly balanced sound for the ultimate all around supercar!
