What about Single Chamber Flows with Turndowns aka DUMPS?

If it's your daily driver you might want to think about how loud you really want it to be. A loud exhaust note is nice everybody knows, but after awhile if it's too loud it's just going to get on your nerves. I have an off-road H-pipe with the American Thunder cat-back and it's pretty nasty at WOT, but the sound level is reasonable at cruising and I can still hear the stereo. Just something to think about.

Dumps will add to the sound and make it sound more bassy (dunno if that's even a word but whatever). The sound pulses resonate off the ground making your car sound more powerful.

u can get exhaust cut-off an install it just after the headers and open them whenever u feel like making some noise lol

mustang5.0 .. yse the single chambers are a lot louder then the packs, i had both w/ dumps and not only are the flows louder, but better sounding imo... 1 week after i put the packs on my car, i had them taken off to put my flows back in... Go w/ flows imo, cant beat the sound
