"Holy smokes! Added perfofmance to the 5.3, looks great, sounds very good. I had the GMC dealer service do the install. Once completed, one of the techs got online to order one for his truck. The quality of Flowmaster products continue to sell themselves. I'm also very pleased with the Customer Service tech with whom I spoke at Autoanything. This entire purchase and product result was truly a '10'." —John M from Fontana, CA bought a Flowmaster Exhaust Systems for a 2011 GMC Sierra, 1500, extended cab, standard bed (approx. 6' 6"), 5.3L V8.

"I have always installed flowmasters on all my vehicles. They sound great and I always get alot of compliments and questions. Great product." —Blake F from Stuttgart, AR bought a Flowmaster Super 40 Series Mufflers for a 2011 GMC Sierra.

"Had to purchase a new exhaust manifold/catalytic converter for my 08 Colorado due to a cracked exhaust manifold. With a new O.E.M priced at over $600 and a Magnaflow just a bit more, of course I chose the proven leader in performance. Along with the Catback system I also installed, I can definately feel a difference. Seems to have more horsepower and quicker throttle response.-" —Reginald R from Beckley, WV bought a Magnaflow Catalytic Converters - 49 State Legal for a 2011 GMC Sierra.

"Exhaust tip looks great and was easy to install, less than 5 minutes. Would rather have the double wall than the single wall as I feel that it would give an upgraded appearance, but it did not come in the size that I needed. Overall nice piece of equipment." —John C from Snohomish, WA bought a Gibson Slash Exhaust Tip for a 2011 GMC Sierra.

"A very pleasant buying experience and installation was a breeze. Everything that needed to be in the kit was shipped and it was delivered when I was told it would be. I could not be happier with my MBRP cat-back exhaust. AutoAnything has my business in the future!" —Luis G from Jacksonville, NC bought a MBRP Exhaust Systems for a 2011 GMC Sierra, 1500, crew cab, 5' 8" short bed, 5.3L V8.

"I put this exhaust on my 2011 gmc sierra 1500 extended cab. The sound is amazing at full throttle and mellow when cruising in town. No drone what so ever. i was averaging 17.3 mpg before the exhaust and now im around 18.5 to 19.5! i would definitely recommend this exhaust to anyone." —Phillip D from Newport, VT bought a dB Performance Exhaust by Corsa for a 2011 GMC Sierra, 1500, extended cab, 6' 6" short bed, 5.3L V8.

"Installation instructions sucked. I watched one of their install videos online, made life a lot easier. After that, it was a piece of cake. I spent most of the install time trying to get them even. Minor adjustments. But it sounds good & looks good. I think any performance gains are lost due to a heavier foot now. Would buy again." —Steven T from Little Elm, TX bought a Magnaflow Exhaust Systems for a 2011 GMC Sierra.

"Installed the S-type system, really good sound. The truck was my graduation present to my son, the exhaust system from his Grandfather. He loves it and I appreciated the ease of installation. A little pricey but I think because of the apparent quality, it'll be worth it in the long run." —Kenneth P from Mobile, AL bought a Borla Exhaust Systems for a 2011 GMC Sierra, 1500, crew cab, 5' 8" short bed, 5.3L V8.

"Top of the line in exhaust systems. very nice low deep tone. Nice trucks deserve the best!" —Richard S from Albany, OH bought a Corsa Performance Exhaust for a 2011 GMC Sierra, 1500, extended cab, 6' 6" short bed, 5.3L V8.

"For the price I wasn't expecting much out of this exhaust. I've had experience with other brands and I was hoping I wouldn't be too disappointed... and boy was I surprised! A buddy and me had this installed on my 2011 GMC Sierra Crew Cab in just over an hour and it was pretty smooth. I went with the single pipe out the side. Only had to make one cut to get the current pipe out and the rest bolted right on. She sounds like a beast now. Very smooth with a mild drone when at a higher cruising speed, but that's pretty much expected with a high-flow exhaust. I still have stock everything else so the throttle response hasn't increased drastically, but there is a difference. My gas mileage has gone down about .3-.4 MPG but I think that's just from wanting to hear her purr. Overall a great experience with MBRP so far. Can't beat it for the price." —Ronald P from Mesa, AZ bought a MBRP Exhaust Systems for a 2011 GMC Sierra, 1500, crew cab, 5' 8" short bed, 4.8L V8.
