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

Reviewed By Donald B (COVINGTON, VA) Reviewed for a 2011 GMC Sierra —7/2/2014 3:13 PM

Quality exhaust, installation not as easy as shown, instructions lack information on dual pipes,dual sport side sweep pipes very tight fit with spare tire and leaf spring, had to redrill mounting tab where you bolt pipes together in order to get them to fit. Good sound, but louder than expected.

Great product. I bought the super 44 series muffler to install with the exhaust system instead of the super 50 series muffler it came with. Best sounding exhaust I have heard in my truck in a while
