Not for people who don't like loud.

I did a lot of research before I bought. Dino - max is a good company. All the reviews I read said nice low growl. The only sound clip I found was this system on was on a Camaro. This was not a good representative of how this would sound on a 8.1liter. This is extremely loud on my truck. That said only took 30 minutes to install. Everything fit perfectly did not even have to remove spare tire. Looks great on truck. Most people see the pipe and think must be a duramax until I start it there is no mistaking it's a big block. Easy install looks great. But really really LOUD.. ...read more

You get what you pay for.

Installed this system on a 2003 GMC with the LQ4 6.0. It has a TON of drone and doesn't look like it will hold up for the long run. Just after a couple months the tip and pipes are already showing signs of rust on this supposed "stainless" system. It looks more like It was a system designed for a diesel with an intermediate pipe to adapt it to a gasoline application. I have already replaced this muffler with a SpinTech just to cut down on the resonance in the cab. It will probably be replaced with a higher quality Corsa or Gibson system come 6 months from now. ...read more
