buddy is wantin to just have a muffler shop run an exhaust on his teg and wants a very deep loud tone to it, so would anyone have a good recomendation to what size to take a shot at he is goin for sumthin maybe 2 1/4 or maybe 2 1/2 but really not sure so any comments would be great.

 

i don't know how deep you're going to be able to get with a four banger. usual no matter what you do. i got a hks hi power and it's pretty deep at idle but still pretty quiet.

my buddy went out and get custom piping done to his b18b hatch, he had 2.5" going into two cherry bomb resonators, and some "turbo" muffler he bought from the muffler shop. it was pretty trothy sounding but prett deep and load in general.

 

i have a 90 teg and i put on a tanabe medaillion concept G ..deep and loving it
