Nice but just not 100%
This system is easy to install and the instructions are clear enough. The welds are good and the bends are clean. All the hardware furnish is quality items. Thar sounds is good not to loud but yet makes you know its there. The only complaint i have is the black paint on the tips started pealing in less than 200 miles of driving. Its not a deal breaker but for the price you would think it would have been powder coated so that it would last. Maybe i gat a Friday or Monday made system. I would purchase again even knowing the issue with the paint so don't let that stop you.

Great Sound For Price! Must Buy!
This is a great product and an even better price. I paid for installation included with the pricing and it only took about a hour for completion.

Just rght
Install this on my 2020 Sierra Denali 6.2 l.... The OEM exhaust just didn't sound like a truck. This exhaust gives the truck just enough rumble without being annoying. It's nice to have a truck that actually sounds like a truck now. Install was easy and only took about an hour or two with some basic hand tools.

The removal of the old exhaust was the most difficult part. I had to cut my my old exhaust into 3 pieces to make the removal easier. The install was so much easier. I did the whole by myself in about 2.5 hours. Great sound and would definitely recommend it.

Sounds decent and looks good. Noticed paints already chipping on tips at bottom and low idle drown isn’t the greatest sounding I was expected it too be a bit louder but cold starts sound great. High rpm’s are decent. A decent value

Not as loud as advertised.
This exhaust is not nearly as loud as advertised. The tips that came with the exhaust also did not fit onto the end of the exhaust pipe.

My Truck sounds like A Truck!
To be honest, its louder than I thought it would be or I wanted, but, it does sound great, and i do love it. Definitely gives the truck a different “feel”. Easy installation nearly anyone somewhat handy can do it! Great fitment!

PERFECT SOUND
Bought this for my 2019 gmc sierra. I was inspecting the stock exhaust and decided it just wasnt going to cut it. so i did some research and bought this flowmaster exhaust system. On a cold start it is very loud in my opinion. it settles down after a minute and then it isnt very noticeable at idle. when you step on the gas is when you hear the pleasant sound of the exhaust. Not to loud and not to quiet. Really i have noticed a big increase is responsiveness and smoothness between gears. Really enjoy the exhaust and would recommend.

Great sound and easy install
Was concerned when I seen the exhaust out the box. But this went together very smooth. Looks and sounds great.. only issue I had was the stock clamp being complete junk and rust.. bought stainless steel replacement and cut the old one off.. Took the afternoon to install due to the stock clamp. Otherwise would have been about an hour install time.
