I think the 2 1/4 exhaust on my b18c5 may be to small.Should I be running 2 1/2? also my AEM cold air is 2 1/2 should it be 3"?aAll this stuff was on the car when I got it.Let me know what you think.
 
intake should be ok - aem makes more pressure by being skinnier
but i would up the exahust to 2 1/2 or 60mm
