(when sidding tip to where it needs to bolt, exhaust is 3 1/2". the tip looks awsome after custom work from shop to make fit. over all excellent looking tip. Truck looks awesome." —Scott S from Arlington, TX bought a MBRP Angle Rolled Exhaust Tip for a 2012 GMC Sierra.

"Gives my newly installed dual exhaust a deeper tone and resonates so much more than oem tip. I feel very pleased with the stainless steel 12" tip with a black logo because it stands out amongst the sea of Sierras with dual exhaust in my city. The larger mouthed angle cut tip represents that aggressive look that RBP is known for. I am very happy and can't wait to show it off to my friends and family." —Angie S from El Paso, TX bought a RBP Round Exhaust Tips for a 2012 GMC Sierra.

"Easy to install and looks amazing! Exactly what I was looking for.. thanks autoanything!!" —Richard B from Boyertown, PA bought a Gibson Slash Exhaust Tip for a 2012 GMC Sierra.

"Once I got pass the fact that I had to cut into my old exhaust the install was almost to easy. Took me about 2 hrs total. But whatever you DON'T TURN ON THE TRUCK when you disconnect the old exhaust. Its sounds loud and aggressive but ruins the flow master exhaust for you at first. The flow master is pretty mild sound almost stock till you get on it then it rumbles. Overall I'm happy! Especially for the price." —Luis H from Reno, NV bought a Flowmaster Exhaust Systems for a 2012 GMC Sierra.

"Great sound, was a little more than I wanted to spend, waited until I got a coupon to purchase. Would have been really easy to install if truck was on a lift. Having install it on the ground was a little more difficult. Still a great system" —Craig D from Kansas City, MO bought a Flowmaster Exhaust Systems for a 2012 GMC Sierra, 1500, extended cab, 6' 6" short bed, 5.3L V8.

"Easy to install and price was best here. Accelerator is now more response and the truck sounds like a V8. Nice note at all speeds." —Marc G from Murrieta , CA bought an aFe Exhaust Systems for a 2012 GMC Sierra, 1500, crew cab, standard bed (approx. 6' 7"), 5.3L V8.

"Easy to install. Nice rumble at idle, throaty when accelerating and a roar at wide open, quiet at cruise. Great sound, not too loud and no drone. Only complaint is when the motor changes from 4cyl to 8cyl you hear it in the exhaust and it gets annoying." —Mike M from Clayton , NC bought a Corsa Performance Exhaust for a 2012 GMC Sierra.

Magnaflow Performance Mufflers

Exactly what I was looking for!

The newer GM trucks have a lot going on with the exhaust, keeping them quiet as can be. I wanted to be able to hear the v8 without it being obnoxious, loud or having a drone at highway speeds. The 22" Magnaflow muffler is perfect, gives a nice deep tone and you can't really tell it's on there until you step on it. Very pleased with the purchase! View more reviews...

Flowmaster Super 10 Series Mufflers

Not too shabby

Too quiet with just the muffler . Had to cut out the resonator. Sounds pretty throaty now probably perfect for a lot of people . View more reviews...
