AAM Competition R35 GT-R High Flow Catted Downpipes

AAM Competition is proud to offer our 3” High Flow Cat Downpipes for the GT-R. This is an essential upgrade to optimize your GT-R’s exhaust system and power. Turbocharged vehicles gain power from getting as much exhaust gas out as quickly as possible. The AAM Competition 3” High Flow Cat Downpipes allow the turbo to spool faster, harder and with more efficiency, giving you more power. With less resistance heat is evacuated faster, so you will also benefit from lower engine temperatures. The result is a noticeable power gain across the entire rpm range as well as the ability to support additional peak power. The 3” High Flow Cat Downpipes are produced from highly durable 16-gauge T-304 stainless steel here in our US facility, which completely eliminates the need for additional support brackets.

For those looking to support higher power levels, optional high-flow GESI HO (High Output) converters are availabe. These ultra high performance high-flow catalytic converters are the next step in high flow cat technology.  The GESI High Output (HO-series) Metal Core Catalytic Converters are the ultimate converter technology for forced induction applications, with essentially no loss of HP!  The GESI High Output Metal Core Converters offer the following features:

  • EPA certified for use in 49 States

  • Full stainless steel construction, including the substrate for outstanding durability all the way to 1500 deg F

  • The GESI proprietary precious metal loading technology ensures greatly reduced emissions, eliminating "Check Engine Light" issues
