Apexi Downpipe and stock o2 Housing??

[Sinclair159]

I cant for the death of me remember if i had to use an after market gasket or the stock gasket from the downpipe to the 02 housing, because im preety sure mine is leaking... i threw the downpipe back on the other day real fast and i was in a hurry so i wanna get a new gasket anyways... my question is?? if i have an apexi n-i downpipe do i need an aftermarket gasket or the stock gasket is the one that fits fine...????

i've dealt with a couple apexi products and they all use this insanely huge gasket. if i were you i'd just get one of each.. this way if it doesn't fit you only lost 5 bucks.. and IMO that's worth the fact that you don't have to take 2 trips to the store.
