I'm thinking about buyin one but haven't seen any performance #'s on it. Anybody with experience with them . 5-10 hp maybe?

If either one gives about the same HP gain then I'd go with the pro chamber. That's what I'm getting in the future. It'll give your exhaust a deeper tone also.

What is a prochamber like? Is it a cross between an x-pipe and an h-pipe? I wish I knew about what went on in that little box.

Prochamber is sort of like a giant H pipe, but a chamber instead of an actual pipe in between.

Anyways, I really wanted the prochamber but I heard sound clips and they were bad. It made stock setups and people with Loudmouths sound really bad. It was weird, hard to describe, but sort of like cars sound more fart-ish or bubbly rather than better.

I have the prochamber and gained a solid 16 hp and 30 ft lbs tq with 1 3/4 lts and prochamber, but cant tell you what the prochamber alone gave me

Prochamber alone won't give much... Its just a bigger Hpipe. You'd be better off with an Xpipe, even if it does sound annoying depending on the setup...
