whats up guys, i made a post before saying that i have a 14829 muffler installed on my tsx, and im looking to go catback, im just wondering what size piping to get and where can i get these pipes, any brands you guys recommend? i was thinking of just going to my local muffler guy and telling him to throw a 2.5 custom piping replacing my stockies. im not trying to throw on a test pipe either and fail emissions, im looking for a nice loudish deep sound. please help me guys, i appreciate it ! im new to the modding game

 

just look around this section of the forum there are a few exhaust threads on here that can give you the information you need. there is an exhaust thread three rows down from this one.
