I've thought about doing that at one time but some people reported how quiet the prochamber is with a stock catted mid-pipe. That's why I want to add high flow cats instead.

IIRC when I was running my high-flow catted prochamber with Pypes axle backs, it really wasn't that loud at idle to begin with, but at WOT is when they got loud but without the annoying cabin drone..

And from my understanding the OEM cats are pretty efficient for a stock exhaust anyhow..
