What exhaust?
 

I have a 2005 Mazda 3 sp23 with a stock exhaust. I am thinking about putting in an aftermarket exhaust after I put in my cold air intake. I have looked at many exhausts and currently I'm considering a catback. However, i was also thinking, is it possible to take a Mazda speed3 exhaust and use it on my Mazda 3?? I love the sound of the speed3 how it is quite when cruising but has a nice sound when you accelerate. Basically what i am wondering is, is it possible to put a speed 3 exhaust on my car? What year? and what Model (HB or Sedan).
Thanks!
