Im running an MRT full turbo back exhaust.

Im starting to find it a little too quiet and want to change stuff after the downpipe.

Does anyone know if the MRT downpipe is the same length as the USDM or JDM strock downpipe?

I was wondering if another catback exhaust will bolt on.

mrt has a new style muffler, it is called cannon/barrel and is 4". it looks similar to the n1 jdm style.it also has a silencer so it might have a better sound.i was considering this set up because i heard the standard box is quiet. email mrt they were very helpful with my inquiry about their products.

Yeah, I should e mail MRT. Thanks for the suggestion.

I really do not want the sound for a canister type exhaust as it is too loud. I have a JDM GC8 STI with a Fujitsubo exhaust and the sound is just right.

I would want to replicate that sound with our US WRX
