I can't decide betweent the two, so i'm going to poll everyone to decide. Heres what i want. I want it loud, but not raspy. I'm looking for that "classic" mustang sound. I don't really know which one i should buy to get the sound i want. I figured some of you guys could give me some advice. I really appreciate it.


on that one. My first modded dyno pull was with only the prochamber, catback, and a tri-ax shifter. I pulled 249.5 RWHP and almost 285 RWTQ with everything else stock. I dont know what planet you are living on, but here on earth the prochamber makes pretty good power in my opinion.
