The AMS Nissan GT-R Midpipe is one of the largest diameter midpipe on the market. Using a large 90mm (3.5”) primary pipe AMS was able to optimize exhaust gas flow and make the engine work a lot more efficiently. Most systems implement two 76mm (3”) pipes that Y into a 76mm primary pipe causing turbulence and unnecessary backpressure. By making this AMS GT-R primary pipe 90mm they were able to greatly improve exhaust flow, freeing up horsepower and improving turbo spool time. With unrivaled fit, finish and performance the AMS Nissan GT-R 90mm Midpipe will easily support any future modifications.
