I run this;

Of course, I adapted my LQ9 6.0 LS to it. Sounds fabulous! Especially with ear plugs, but what the hey.
And no, I can't get a good audio track of what it sounds like. I either get lots of wind noise followed by banging and scraping sounds when my phone falls off, or it rings and I have to pull over to remove the duct taped phone from the bumper and answer it. Lol!
Seriously, if you want a complete FabSpeed set up including including headers back to the center exit point I'd make them a good deal. All stainless so no rot and nothing has been cut. It will need new gaskets regardless. I imagine it would be pretty loud but I bought the car with a bad motor so not 100%v sure on that.
