LT's And SLP LM?
 

From what im seeing, dynomax bullet is the way to go when it comes to replacing the resonator, does that help the tone so it doesnt have a raspy tone like ive heard it has with resonator. As for the bullet, 18 inch is the size right? Thanks for any help.

The Dynomax bullet may help, but unless you're going to run cats, I don't think it's going to sound too pleasing. Mind you, I haven't heard a LM with headers and an off-road Y-Pipe in person, but from what I've read and the sound clips I've heard, I wouldn't recommend it.

I love the way my system sounds. It's still quite loud, but not raspy, even with the original resonator.

My suggestion would be to buy a couple high-flow cats. But that's just my two cents.
