Corsa Performance Exhaust Reviews


Mild to Wild

Reviewed By Joseph H (HUMBLE, TX) Reviewed for a 2011 GMC Sierra —1/21/2016 3:08 PM

It sounds desirably mild during normal driving, but provides the thrill of a top-fuel dragster at wide-open throttle. I'm not impressed with the appearance of the clamp that holds the tip on, makes it look cheap. I may have an exhaust shop weld it on and remove the client.

Banks Monster Exhaust System Reviews


Basically an overpriced tailpipe for the Duramaxbut looks good.

Reviewed By Steve M (Vancouver, WA) Reviewed for a 2011 GMC Sierra —7/7/2014 8:19 PM

I couldn't stand the stock musket style tailpipe on the Duramax. I opted for the Banks due to past experience plus their claim in runs cooler than stock. Installation was easy, quality looks good. The only thing I didn't like was they design the system to have a tailpipe piece inside the exhaust tip. I believe they do this to help with prevent heat discoloration on the tip. I cut the tailpipe piece back so the tip doesn't have another pipe inside it. Looks much better and so far no discoloration
