CORSA 14866 Cat-Back Exhaust System

The media could not be loaded.  I’ve had this exhaust on my truck for about 7 months now and every time I start my truck up I don’t regret going with a more expensive/quality exhaust. I have received quite a few compliments from other people on its sound as well.I did not do the install on this exhaust so I couldn’t tell you the difficulty level of putting it on. I believe it only took about 2 hours for the mechanic to put it on for me.I did notice at first that there is a few week break in period of this exhaust. I bought it in November so I would warm up my truck in the morning before driving and noticed that there was a noticeable amount of soot or carbon build up on my rear fender from the exhaust for awhile. Nothing that couldn’t be cleaned off. But it did go away after a few weeks.Before purchasing I did a lot of research on other exhausts and I am happy with this choice. I believe that Corsa will make any Chevy sound great. It has a very distinct sound. Not too loud with minimal drone. Drone is only noticeable in V4 mode from time to time. Idle is not obnoxious. You may wake your neighbors on cold starts like in the video. This exhaust really comes alive at over 2500 RPMs. I did just about have a heart attack while pulling a trailer when the truck went into grade braking on a steep hill. The exhaust pops and crackles really loud when in tow mode as well.Noticeable performance improvements are minimal. The only real difference I noticed in performance was in my RPMs. It felt like the truck was less restricted than before. When in park I can get a quick rev of the engine over 4000 RPMs.You will definitely make the right decision with this exhaust.

I had a Borla ATAK on my Mustang. Also a CORSA Extreme. MBRP had the best looking mufflers, and Borla the best sounding. CORSA was a compromise between the two. Neither the CORSA or Borla droned and the Corsa was almost too quiet on the highway.On my Silverado 6.2, the Borla ATAK system droned a lot. A LOT, even during deceleration! I switched to this CORSA and there is no drone on the highway at any speed, BUT it does drone during mid throttle acceleration in the mid range of gears quite a bit. Not enough to remove the exhaust but a noticeable annoyance nonetheless. Once the exhaust warms up this is not as bad, but still there.Design wise I'm just frustrated that Corsa does not offer a dual rear exit kit like Borla. Borla makes great kits in that regard, and the exhaust tip options they make for GM for the Silverado/Sierra are awesome too. I hate the huge side exit for visual and sound reasons.But as another reviewer said here somewhere, Corsa for GM and Borla for Ford. They are right. Overall this is def the best sounding system on the GM pickup 6.2 that I have heard. The Borla sounded great on the outside but bad inside. This one is great all around.

Installed easily and fit perfectly on 2017 GMC Sierra. The chrome dual tips are high quality. This system rumbles and roars when you want it to. During easy highway cruising the sound is acceptable and does not disturb passengers, which was a primary concern when purchased. Slower cruising can cause a minor droan and a louder sound for some reason but it is not bad enough to cause any complaints. Overall great quality, fit and finish and installation at home in driveway is easy enough. Be warned about removal of the stock system in the driveway however, we had to use a sawzall and cut the stock tailpipe off the muffler contrary to directions. This may differ on other truck models or years but had to cut the stock tailpipe on 2017 GMC Sierra.

Awesome product. If you are looking for a cat back exhaust system that looks and sounds great. This is the one for you. When you first start the truck up when cold it's definitely noticeable. As it warms up; it gets quieter, but sounds so good. Reminds me of a Corvette. As you cruise the system will drone when it goes into 4 cylinder mode, but it's usually when you're below 50mph that you can hear it, but i hardly notice it. At highway speeds 70+; it doesn't drone. If you've disabled the cylinder shut down you won't have this problem. This system is worth it. It is my second Corsa system and i will continue to use them. Definitely would recommend if you are in the market for a system that you want the perfect sound from.

Nothing but good things to say.. no drone.. great sound... been asked by several people what exhaust I am running in my vehicle as they are beyond impressed. When I dealt with Corsa's customer service about which exhaust to buy they were very helpful and answered every question .... in contrast I called Borla and they were completely rude and didn't even have a product for my vehicle... I am loving every start and mile with this new exhaust... best exhaust I have ever purchased. I am running this on a 2015 Silverado with a 6.2 V8. CORSA for life!

Easy to assemble. Only problem is that the tips for the exhaust did not come in the box. Amazon did refund portion of price to cover cost of the tailpipes (tips)

I finally went with a Corsa exhaust and I am glad I did. I have owned Borla, Magnaflow and I believe this to be the best sounding exhaust out of the 3. Loud when you get on it, quiet when you are cruising with no drones. I cant wait to add some Kooks headers and Kooks green cats when the funds become available. Sorry forgot I had a SLP Loudmouth exhaust on a Trans Am, sounded awesome but the highway drones were awful.

Exactly the sound I was looking for on my 2017 GMC Sierra Denali with the 6.2. V4 drone is noticeable but not unbearable. It will wake up your neighbors on cold start but after it warms up it’s not too loud unless you get on it.
