hi all... new on here. had our 5 for about 6 months now, was wondering if an aftermarket 3 exhaust will fit underneath, any experience will be helpful. also I am planning a diy intake, may be a few days from now but will keep yall posted with pics if i can figure out how to put pics on here, lol

 

As for an intake I bought the 60 dollar injen ripp off from ebay. Its for a Mazda 3 but will fit the 5. I went with a 2.25 cat back with resonator and borla muffler as an exhaust. Well I don't know if the 3's exhaust will fit the 5 i doubt it but I could be wrong. The muffler is on the 3 is not in the back like the 5's.
