3" stainless constant-diameter direct-fit cat-back exhaust cuts backpressure up to 94% and improves 0-60 mph acceleration times by 4.5%.
Banks' 3" constant-diameter Monster exhaust pipes—formed of heavy-duty stainless steel—bolt behind the catalytic converter to slash backpressure up to 94%, improving 0-60 mph acceleration times by 1/3 of a second (4.5% quicker). The straight-through 3" Monster muffler delivers a throaty, yet civil, exhaust note and more than doubles stock flow (up to a 141% improvement). 6"X5" weld-on ob-round polished-stainless angle-cut rolled-edge tip (patent pending). Installation of the direct-fit system is bolt-on easy. Fully compatible with GM's factory warranty, the entire system is covered by Banks' lifetime warranty.

Wanted something better than Flowmaster
I own a 2004 Chevy silverado with a 5.3 Engine. I had a flowmaster exhaust on it! But wanted something better. So i did some looking and found Banks. And i couldn't be happier! Easy to install and looks great? And for performance wow such a great upgrade It gets up and goes with such ease.

“We went to the source of diesel-engine performance, Gale Banks Engineering, and struck gold. Not only did it take one stop to buy and have our parts installed, but the parts worked as advertised and the results were awesome.”
