ok so i have a question my current catback exhaust set up will not work with my rear bumper on my new bodykit as it will not look proper with the cut out for the muffler on it as its for a round muffler and mine is an oval, so i was wondering i have the 2.5" thermal r/d catback exhaust and was wondering if i could switch the muffler part to one of two sized mufflers and it'd still work i'm not looking for performance gains as we all know my car is not set up for performance but i figured i'd post it in here as its still performance related the two muffler sizes i'm looking at and wondering if it'd work are:
1st one: tip diameter: 96mm, pipe diameter: 60mm
2nd one: tip diameter: 120mm, pipe diameter: 75mm
would either of these work with the 2.5" piping and not hurt my car in anyway please let me know and would it just be a matter of cutting the thermal muffler off and welding the new one onto the catback piping?
thanks for the help =)
