It sounds awesome when you get on it and is quiet when you're cruising at highways speeds with zero drone. I will definitely be purchasing this again on any V8 vehicle I have in the future.

Corsa exhaust 2018 gmc sierra slt 5.3

I can whisper while driving and can still hear clear has day, my off road tires are actually louder than the exhaust at cruising speeds super easy to install, I did remove the factory exhaust in one piece, corsa says to cut it for easier removal but if you have a car lift at your disposal it's just as easy not cutting it, I did have to get a new bolt for the clamp off the cat but that's was the only thing I had to replace! I still reused the clamp but the bolt was long gone from MN winters, this exhaust is only loud on Initial start up other wise a very quite exhaust. It looks factory as well, and corsa customers service is fantastic really truly are 10/10 for customers service! I'm still waiting on my CAI to arrive but I'll leave a review for that also

Makes me smile! The double tip looks awesome too! And cruising on the highway is nice as it's not crazy loud. I've had many loud exhaust but drone on highway was terrible. With this can comfortably talk in cab with passengers or on phone while cruising on the highway! Was about 6 week wait to get my catback in Canada! Thanks Corsa!
