o2 housing and stock downpipe

[guitarhero14]

I wasnt able to find the answer to my question when searching.

I would like to get a o2 dump from 122performance and they are 2.5", will this fit on my stock downpipe? Thank you.

Yes, it will fit. You really need to look at a downpipe before the o2 housing. Apexi and RRE has downpipes that are 2 1/2" until the flex and then go up to 3" after the flex.

If you just want to dump your stock o2, you can pick up a used o2 housing cheap and do this to it (no down time):
