Was just wondering, if anyone has received any codes after installing a y-pipe and what the procedure would be after? A buddy of mine is planning on installing a y-pipe on his 01 and was just wondering how the o2's will respond with the flow of the y-pipe? Any input would be greatly appreciated! I actually have tried to read the stickies and search but did not find what I was looking for! Thanks in advance fellas

you should not get codes after installing a y-pipe.

i've had mine on for 7 months and haven't gotten a ses yet. (knock on wood)
