Ok, after looking for a quieter exhaust then whats on my car atm( N1) I found out many mufflers wont fit our cars as it has such a short overhang in the rear. so Ive made the choice to go with a twinloop, will I have any trouble fitting a twinloop from an Integra Type R ? do the CTR mugen t/l and ITR t/t differ at all ? I mean in dimesions . cheers
