I was reading some post's on here. and im about to buy some Headmen headers (summit) HED-68470 and then the Headmen Y Pipe (summit) HED-17470... and then a muffler.. but i seen you guys talking about a one chamber and that they are very loud... loud as in jacked up hill billy pickup truck loud or Deep loud? and is this one? (summitracin.com) FLO-325108 ? or what kind of Muffler should i get to go along with my new headers and Y pipe?

Get a Hooker-Cat back. Listen to Marks a Shield It sounds sick. Nice and loud.

Thanks. To answer your question, I've never heard the 1chamber, but you might get in trouble with the noise police if they're D1cks where you live. And I would think it would outflow the Hooker aero chamber.
