Great sound for the money and not too annoying, easy to install.

Easy to install. It took me about 1.5 hours on my garage floor by myself. It gives off a nice deep tone with no noticeable drone. It was the perfect compliment to make my new truck sound like a truck! I shopped many exhaust systems... I’m glad I chose this!2020 Silverado 5.3

Me and my dad replaced the OEM in less than 4 hours, easy instructions and easy fit, I'm not mechanically inclined, so if you are even a little bit this will be easy.It sounds freakin amazing! Not too loud or overpowering when idle just a nice low growl, but when you open it up, it grottles beautifully. Love it.

Easy to install about less than an hour. Sounds good inside the cab and outside. Definitely lets you know you have a V8 compared to the stock exhaust. You can feel the power response when towing and hauling.

i bought mine in Nov of 2019 and i live in Los Angeles (no snow here). The exhaust has already rusted and broken at the dual exhaust exit on the muffler itself... not quite the quality i was hoping for. Unless Flowmater will warranty it... it will be a waste of $550.

Sounds great. I wanted something with a rumble but not too loud. This is perfect and was very easy to install.
