I have MAC long tube headers with MAC Prochamber mid pipe and Roush Axle backs. It sound super screechy with the pro chamber/roush combo. The only other Hpipe for 2013 V6 seems to be lethal performance. Anyone run MAC LTS with this Hpipe?
I know on the SN95 platform the MACs need a MAC specific mid pipe. Not sure about the S197s, call MAC and ask or email them. That said its still going to sound like that with a H pipe. The Roush mufflers are notorious for this sort of thing, I'd swap the mufflers out before I did the prochamber. Throw some Magnaflows on there and profit.
Long tubes with an X or h pipe will sound raspy as hell with any muffler.
Its just a product of the 3.7.
Once you start screwing with the stock mid pipe on the cyclone the sound goes to ****.
