Gibson Exhaust Systems Reviews


2008 GMC Sierra build up

Reviewed By Richard D (LAFAYETTE, LA) Reviewed for a 2008 GMC Sierra —7/22/2015 10:43 AM

I had Gibson headers & exhaust system on my 05 Ram & couldn't wait to get the money together to purchase this Gibson exhaust for my GMC Sierra! Please cut the old exhaust in half to remove easiest way. Install of Gibson was easy I did it myself on a lift. I did opt for the stainless steel version and it looks & sounds like grown man stuff! Just buy it the system you will not be disappointed. Auto Anything is AWESOME! Got it to me quick! Will be buying more items to complete my build up!

Magnaflow Exhaust Systems Reviews


2015 GMC Sierra Denali 6.2L Magnaflow Cat Back Exhaust

Reviewed By Rick T (East Peoria, IL) Reviewed for a 2015 GMC Sierra —7/4/2015 10:56 PM

Overall, very pleased with the Magnaflow exhaust. Two of the four hangers were off a bit and had to be adjusted, but I am a perfectionist. They probably would have been fine but now they are perfectly aligned. Exhaust has a very nice throaty sound when accelerating and quiet when cruising. Has a pretty good rumble when starting cold. Not too crazy about a five inch exhaust tip. Kind of makes it look like a diesel truck exhaust. The more I drive the truck with this exhaust, the better I like it.

Flowmaster Exhaust Systems Reviews


Great sounding exhaust

Reviewed By Jack D (Somerville, TN) Reviewed for a 2001 GMC Sierra —6/16/2015 5:59 AM

Flowmaster has always made great sounding exhaust. I had to remove an aftermarket hitch because the side brackets were too low and my son wanted the exhaust out the side. I found a factory hitch that fit with no problems. Other than that, which wasn't Flowmaster's fault, the exhaust install was very straight forward. We are very happy with the look and sound.
