IS the apexi going to be OK to run a greddy turbo on? I mean oviously 3" is probably the best, but considering the downpipe is only 2.25", would this exhaust be ample enough? I figure its the straightest, and least restrictive of all cat-back systems. Is the N1 piping 2.25" or 2.5" or somewhere in between? By the way, the car has no catalytic converter.
