The highly anticipated AAM Spec 2.5" Test Pipes for the Nissan 350Z and Infiniti G35/G37 are finally here! After servicing and installing several of our competitors designs we decided to make a higher-quality test pipe that meets the demanding reliabilty expectations of our customers.

In addition to having poor fittment, many of the test-pipes on the market are constructed of thinner, lower grade stainless tubing. Not only are these units highly succeptable to fatigue and cracking on near stock 350Z's and G35's, some customers with supercharged and turbocharged 350Z's have torn apart the weld joints of these inferior test-pipes. Made out of 2.5" mandrel bent 16-gauge 304 stainless steel to ensure the hightest reliability and quality, the AAM Spec 2.5" Test Pipes replace your vehicles restrictive units to allow the higest possible exhaust flow.

Dyno testing has shown 8 to 10 RWHP gains on a near stock Nissan 350Z and 20+hp gains on a turbocharged Nissan 350Z! The AAM Spec 2.5" Test Pipes are for off-road use only and are a direct bolt-on replacement of the factory units.
