Best Exhaust for 1970 Challenger 340

Hey, are there any recommendations for exhaust on a 340 Challenger? Right now, I've got stock exhaust manifolds that go to cherry bombs. I've looked into TTI since a lot of people recommend those, but I was wondering if there were any better alternatives. I'm looking for something that will give it a good sound (Loud, choppy, maybe higher pitched than an H pipe) and could also improve the power a little.
