"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.
"For the price you cant beat it. Very low drone. Not to loud causing great sound when you get on it. 6.2 sounds great!!" —John H from Holbrook, NY bought a MBRP Exhaust Systems for a 2011 GMC Sierra, 1500, extended cab, 6' 6" short bed, 6.2L V8.
"I am SUPER happy with how easy it was to install this exhaust. The sound is everything I was hoping for. This is a great value if you are looking for a good exhaust at a bargain price." —John B from Fort Mohave, AZ bought a Gibson Exhaust Systems for a 2011 GMC Sierra, 1500, extended cab, 6' 6" short bed, 5.3L V8.
"Love this exhaust, really happy I did the research and that I went with Auto Anything, the best price and they will beat the price of anyone (it will be less). Gas is not improving because I cant keep my foot out of the accelerator. My fault but it just sounds so good, bought the touring one, just right, nice at start up and when you get in it, but almost factory at highway speeds, no annoying drone noise. Once you get the factory one off (follow the directions load up the rubber hangers with W-D 40 and will make your life easier) the new one really goes right on. Maybe 45 minutes with two guys taking there time to line everything up (dual exhaust coming out the back). Hardest part was the clamp that holds the pipe to the catalitic convertor." —Alvin R from Rochester, NY bought a Borla Exhaust Systems for a 2011 GMC Sierra, 1500, crew cab, 5' 8" short bed, 5.3L V8.
"I have had trouble with making the exhaust tips line up the same and not point down towards the ground and the tail pipes were right against my spare tire. But the good news is that MBRP has been very helpfull in correcting these issues even offering replacement parts free of charge. Its not as loud as i thought it would beeather. But I would reccomend this product." —Anthony S from Adrian, MI bought a MBRP Exhaust Systems for a 2011 GMC Sierra, 1500, extended cab, 5' 8" short bed, 5.3L V8.
"The exhaust looks good and sounds great. The only thing that i don't like is how it sounds at an idle. When your accelerating or mash the throttle it sounds great." —Kevin C from Saugerties, NY bought a dB Performance Exhaust by Corsa for a 2011 GMC Sierra.
