i made a post in s2000 talk, but i decided it was in the wrong place so im moving it. i just dont know how to delete the old one so....

i am soon to be in the market for a test pipe and i was looking around and found a t1r CEL fix. one is straight and one is an elbow shape. i have heard back and forth that the berk TP has it already and no CEL, but some do for some reason. do you think that the elbow shape will work better than just the spark plug anti foulers? here is a link to it T1R CEL fix lmk what you guys think



also i have been debating on which size to get the 60mm or the 70mm. will both fit stock systems?
