Great Exhaust System

Reviewed by Jacob B (La Crosse, WI) Reviewed for a 2011 Chevy Silverado — Jan 14, 2017 7:21 AM

Great system for my truck, stainless looks good. Great sound and performance very little drone none driving around town and barely any on the highway. Definitely recommend buying different clamps if you are going to install this yourself, buy quality band clamps 2-2.25" and 2-3" clamps the ones included aren't very good compared to the exhaust. Also directions tell you to reuse the v-clamp off your stock exhaust by the cat and they are almost always rusted on so buy a new one of those as well.

You can feel the added hp

Had a little trouble getting it to seal to the factory pipe , but after that the rest of the installation went well. The sound is just right, not too loud with a little bit of drone inside the cab and only slightly louder than the factory system at cruising speed. I really like the way the dual tips exit side by side behind right rear tire.

Very nice exhaust.

Ordering and shipping went without a hitch. Installation took about an hour start to finish. All pipes, hangars, and clamps were quality and fit exactly in factory hangar locations. No modifications necessary. Sounds great! No issues when AFM kicks in. Haven't checked if there is a change in mileage as of yet.
