where can i buy the racing beat muffler (not the cat-back ) i want the same one from the mp3. thanks

 

u can try mazdastuff.com. when i was gonna buy one i emailed them and they said it was just the muffler. or u can just buy the exhaust and cut the muffler off if u want. i heard that it's still pretty loud so i ended up not buying it.

 

oh and u can try a local dealership too.
