Overview

The AAM Competition AAM37E-TP25 is a set of test pipes designed for off-road performance. These pipes replace the factory Nissan 350Z High Flow Cats and are constructed from 100% T304 grade stainless steel. The mandrel-bent piping is hand-assembled in the U.S.A.

By removing the catalytic converters, these test pipes allow exhaust to flow more freely, which AAM Competition states can increase peak engine power and torque. The 2.5" diameter pipes are intended to provide the highest possible exhaust flow for performance enthusiasts.
Show original supplier description
The AAM Competition AAM37E-TP25 test pipes are engineered for enthusiasts seeking maximum exhaust flow and performance gains. Designed to replace the factory catalytic converters on the Nissan 350Z High Flow Cats, these pipes are strictly intended for off-road performance applications. Constructed from 100% T304 grade stainless steel, the test pipes feature mandrel-bent piping for optimal flow and are meticulously hand-assembled in the U.S.A. This construction ensures durability and a superior finish, providing a perfect fit for your vehicle. By eliminating the restrictive catalytic converters, exhaust gases can exit the engine more freely, leading to increased peak engine power and torque. These 2.5" diameter pipes are specifically designed to maximize exhaust flow. The product literature indicates that they add an aggressive exhaust tone and an estimated 8+ RWHP. Free ground shipping is included within the contiguous U.S.
