I'm running a DNA truck series muffler click here for a sound clip

 

that sounds pretty good i like the camera shake when you rev it pretty intense did you see any gains from that muffler

 

There's a couple other vids under my name too...

When you tromp on it sometimes, you can hear the air being tossed out the exhaust, lol (the "whoosh" kinda noise)

There was a bit of improvement according to the butt dyno, and the gas mileage did improve a bit...

 

I'd run flowmaster, but i make minimum wage, and cant afford it so... the 22.oo thrush glasspack is the one i ordered, i might swap it out when i save money
