I like the sound alot, it does wonders for my GMC. Happy to havr. Also a gas saver. I did have one of the black tip scratched when it was shipped. Called and sent a picture. It was well rapped and boxed but scratched when put in the box. Called, sent picture of it and was told another was shipped to me. Not here yet must be coming by dog sled!

Corsa Performance Exhaust Reviews


Awesome Exhaust and Sound

Reviewed By Robert R (Fort Worth, TX) Reviewed for a 2014 GMC Sierra —8/2/2016 2:55 PM

Really happy with the CORSA. I have a 6.2L and this exhaust really wakes up the sound of the motor. The factory exhaust was asthmatic and made the engine sound small and pathetic. The CORSA gives it the baritone the V8 deserves. Other people complain about drone but I had disabled V4 through Diablo Sport inTune so I did not have drone. The only complaint I would have is the price but I am happy overall.

Install

Reviewed By John V (Sparks, NV) Reviewed for a 2014 GMC Sierra —7/23/2016 3:02 PM

Good exhaust, very difficult to line up dual exit system. Sound is loud on start up but not loud at cursing speed.. Worked with MBRP to get system lined up, good tech service. I am good with my hands but surprised how tough it was to get dialed in.
