Review on Borla 400130 Universal Performance Muffler by Kevin Bucher

I bought this muffler for my 2013 Sierra and am very impressed. I didn't want to buy the Borla Cat Back system because it was $1400. I searched until I found the muffler they use on this system and bought it individually. Perfect! Quiet in the cockpit while driving on the Autobahn and when you step on the gas you can hear everything! The exhaust at idle is enough to let you know it's out of stock. I highly recommend buying this muffler if you want Borla sound and performance at a great price! Do that!
