What kind of sound are you looking for?

This would help me out a lot especially, so I can try to set you up with an exhaust you won't regret!

Ok, well, for a quieter, mellower exhaust, with extremely minimal interior sound at all, go with a 70 series Flowmaster or a 24" Magnaflow. the flowmaster I would say should sound better than the Magnaflow for a 6.0, but the Magnaflow will still have an awesome sound w/ a more noticeable power increase than the Flowmaster. I have a 70 series si/so setup on my truck currently, and I couldnt be happier. Under acceleration, its a smooth, mellower tone, quiet inside, and under freeway cruise it's DEAD QUIET inside!!! No drone inside ever, awesome performance, aggressive sound, and I get tons of compliments on the sound. I've got this setup on an '00 Chevy 3500 Crew cab long bed, and it's used to tow a 24 ft. race trailer almost every weekend during the summer and spring, the last thing I need is drone from the engine working harder. It is a little bit louder inside when towing the trailer, since the sound waves bonce off the front of the trailer, but ohhhhhh it sounds so sweet. Whenever my dad's towing he cant help but floor it from a dead stop (which is why he never has gas after I drive it ). I finaly made a sound clip yesterday from outside, it gives a pretty d**n good idea of how it sounds. It should be up and running on the web within the next few days.

I also know a family w/ a denali 6.0 w/ 70 series, and it sounds INCREDIBLE!!!

Magnaflow, I've never really heard on a 6 liter, but I'd imagine it sounds just as awesome!

Sounds like you need to keep your stock exhaust and invest in a Westers PCM.You would get more bang for your buck if your looking for a little extra giddy up.
