I ordered the extreme set thinking it might be too loud. Instead I was a bit disappointed that it was so quiet. Upside is it looks great sounds nice low rumble and no highway drone what so ever. Also actually getting a mile per gallon better mileage on my last 2000 mile trip after I installed it. Installation instructions are poor. Exhaust pipes somewhat confusing as to which end goes to rear and forward from muffler to tips. I figured it out after a few tries. Better instructions would be great

Worth every penny

Reviewed By Alec V (DALLAS, TX) Reviewed for a 2002 Chevy Avalanche —2/18/2016 6:37 AM

Installation took 2hrs only because i didn't have a saw saw and getting the stock off the hooks is a bitch! If u cut the hooks off and the stock exhaust in half you will save an hour, the actual installation took 10min! So easy. Getting the stock exhaust off was so worth it the Mbrp exhaust sounds Amazing! And is a lot louder, happy with the product and notice a lower idle range in the truck so I'm saving maybe 1-2 mpg.

Borla Exhaust Systems Reviews

Nice sound but not loud enough

Reviewed By jesse b (Saint Peters, MO) Reviewed for a 2007 Chevy Avalanche —4/17/2015 2:44 PM

I bought the cat back system and it gives it a better rumble over stock but not as loud as I would like. With that being said I started the truck up with only the catalytic converters on and it was tame in comparison to what I have heard with open headers on other v-8s. I might have to purchase the high flo cats as well
