I cant get over how good this things sounds. I have a 2017 Silverado 6.2 I kept the 3rd cat and resonator. I just replaced the muffler and it has a very deep rumble, no drone and if very quite on the highway 100/100 its perfect!!

I think its perfect. Very aggressive, loud but not to loud. When you get on it you know it's there but quiet when your cruising on the freeway. I left the resonator on and just did the muffler swap and added a chrome tip. I do hear a little baffling but i can't tell if it's the tip or resonator. All in all a great product and a great sound.

I am in love. The XR1 sounds amazing. After reading review after review from every manufacturer under the sun, I finally settled on the XR1 for my โ07 Esky 6.2. I left stock exhaust manifolds, resonators and cars. Just added the muffler. Shop charged me eighty bucks to โZeusโ it into place and I was on my way. Itโs the perfect LS 6.2 sound.

Does NOT directly fit a 2016 Chevy Silverado 2500 with the 6.0. New muffler was shorter than the stock. Had to add two 90 degree elbows
