Post BPS Rapid Exhaust vs BPS Q Muffler
Has anyone ran the new BPS Rapid Exhaust yet. Does anyone know how much louder it is than the Q. Could you notice the increase in performance?

I’ve heard both so I can’t speak on performance but it is a good bit louder.

Yeah it's loud. It's similar to a voodoo with the baffle in it imo

I’ve never heard the Vodoo exhaust, but have heard the BPS Duals and BPS Crossover. How does it compare to those?

Yeah it is. Without the baffle you can hear it from "sea to shining sea" lol

I’ve been looking at getting the one with the baffle in so I’m not sure how much that quiet’s it down.

My new style Q is loud. I can’t imagine having anything louder than it is.

I think the q is pretty quiet. One huge variable here is camshaft. My stage 1 motors are not too loud even with a voodoo. When the cam goes in it's a whole nother animal and usually requires hearing protection, lol

My rig never ran faster than what it did with the Rapid. But, I just don’t do the noise we’ll, at all. So...went back to the Q...got the Flex Q this time. Better than stock performance....not Rapid performance....of its louder than stock...it wouldn’t be by much.

I completely agree.

I can tell the difference from aftermarket cam to cam as well.

I had a .305 cam and it was crazy loud with the a voodoo.
Went to a Willey .308 and much better. (Still loud with a voodoo of course)

It was explained to me the the exhaust duration on the cam profile has a lot to do with it.

Maybe that’s it... I have one of Nick Peltier’s cams with the new style q. I wear muffs when scouting and I’m darn near deaf lol
