Does anybody know what the flow rate is of the stock JK muffler? I have an 08 Rubi Unlimited if it makes any difference whatsoever, not that I think it should. The Dynomax competition exhaust is rated at 2,000 scfm, and their axle-back kit is rated at just 700 scfm. I am just wondering where the stock muffler falls. Anybody?
