I love mine the way it is right now. But its just stock manifolds and cats with an SLP Loudmouth 1 resonator dumped.

When I eventually get some longtubes and ORY, I am wanting to go with a full 3" single exhaust with a 5x8x6" oval body Magnaflow race muffler and either dump it or side exit exhaust.

Im very interested to see your results. Any chance of a good sound clip once you get it in? Right now I'm not running any muffler or anything...took the catback off. It's loud but sounds like smashed ******* I took it off thinking it may get me a little at the track.

I like the way my truck sounds but i don't think you would get away with it south of the 49th for Starters i have a very mild cam probably a notch or 2 above stock

where have you ever heard a smashed *******?

interesting...lol

I will say the 4" in/out dynomax race muffler (not bullet) sounds like sex all over the rpm band.
