Will the duel exhaust that's in the coupe fit in the sedan? The sedan would look so cool with the duel exhaust. Why doesn't Infiniti put the duel one in the sedan? You'd probably get a couple of extra HPs also. Is there an aftermarket exhaust that would give you the duel muflers?

do a search man. this h as been discussed. there is a charcoal canister where the second exhaust would have to go.

the easiest way to do this would be to move the battery to the trunk (not likely from the factory), then move the canister to the engine compartment where the battery was.

then you will have room to run the second tailpipe.
