i love that sound but i freaking hate that it sounds like it's clogged up. i want it to be high pitched like the bassani set-up on top of the page, but i don't want to lose that 'thunderous' sound that this set-up makes. i know the bassani doesn't have it. might the freaking 2chambers be f****ng it up? if so what muffler would give me that scream i want from the prochamber. basically, my perfect sound would be what i heard with this set-up but w/o it being 'clogged', do you understand what i mean. also, how would the l/t affect the sound since i'll be getting those? please help me out cause i want to do it right the first time.

what i mean, is that burbly throaty sound when they let go of the gas

jr, thanx for the vids, that's the "openess" i would like to hear with l/t and prochamber. can it be accomplished? the only thing that, in my opinion, your exhaust is missing is that burbly sound when you let off the throttle. thanx again

thanx man. i guess i'll just stick to whatever comes cause i rather have more hp than the sound. i'll still like it, i think. l/t,pro,xr1s
