are there any differences between the 09-10 5 speed Coupe exhaust and 05-07 ST exhaust?? or are they the same exhaust? all i know is that the 5 speed coupes dont have the rear resonator and dont think the ST does either.

I believe that the 09-10 coupes have a front resonator and all that stuff to make it quieter, the ST doesn't have that to have a more freely flowing exhaust.

I am not, however, 100% sure, but I have an '09 5spd sedan and it has a basically normal exhaust which just sounds cool inside the car but is rather quiet outside the car.
