2020-2022 GM 3.0L Duramax 304 Stainless Steel Cat-Back Performance Exhaust Kit - Single Exit

Paired this upgrade with the S&B cold air intake along with intercooler piping. Installed at the same time. Can hear a slight deeper rumble at the exhaust and overall more noise when accelerating. As the other reviewer noted the exhaust tip has rotated once on me so far as the last two connections does not have the best support. In the future i plan on adding another exhaust clip/clamp at the end of the run to better support the exhaust. In addition the kit did not include the additional rubber hanger you will need to complete the install. For $600 you think that would come. The truck already has a straight pipe so it's just a bigger diameter to allow for better airflow and power. The truck is peppier. Wish it had more rumble but limited with the cat and it being a 3.0. Overall the kit was straight forward to install and good quality material. Would recommend.

Very significant increase in appearance; it's a thick pipe. There has to be a better way to get the last two pieces at the exit end from rotating. You have to tighten the snot out of those last few connectors. No significant sound difference. Ceramic coated tip is nice, looks real good on the truck. Install way easy, wish it was a hair louder, but it's it's baby diesel so you get what you can.
