Rock Basher™ 409 SS Hi-Tuck Cat-Back Exhaust System with Single Rear Exit by aFe®. Exhaust System Type: Cat-Back. Exhaust Tubing Material: 409 SS. Main Tubing Diameter: 3". Exhaust System Sound: Aggressive / Loud. This top-quality, unique cat-back exhaust system defies to be replicated. aFe POWER introduces the all-new 3" stainless steel Rock Basher series exhaust system. Large, 3" mandrel-bent 409 stainless steel tubing outflows the restrictive OE exhaust to increase horsepower and torque. In testing, the Rock Basher cat-back system resulted in gains up to +9 horsepower and +8 lbs. x ft. of torque, as measured on their in-house dyno.
It was rough getting the factory one off without a lift, but install of the rock basher was easy. I recommend getting a new clam clamp for the piece connecting to the manifold as mine was hard removing.
