When we say we test our parts we weren’t playing around. We took one of our Wrangler projects to Batlground Engineering for dyno testing. Batlground is one of the hottest motorsport shops in the southeast known for their drag racing and drifting. Almost new this 2009 Jeep Wrangler 4dr, with 1600 miles, got our Rugged Ridge ORV 4″ Lift Kit and our Black Rugged Ridge Wheels with machined lip wrapped in 35″ Goodyear Wrangler MT/R with Kevlar provided by TreaDepot.com before we did the test. So depending on application and wheel/tire package your numbers could vary. If you have a newer JK Wrangler with 3.8L you know the motor is a dog and when you add an offroad wheel/tire package it just gets worse. So we wanted to know exactly how much wheel power we were putting to the ground and what performance gains we could expect from our intake/exhaust.

Which one of your exhaust systems was on the Jeep when it was dyno'd? It sounded great. Thanks for posting the graphs.

Is the normal cat back system the same diameter as the stainless system (2.25")? I agree it sounds good!
