I am looking into gettin an aftermarket o2 housing for my car, i was wondering if anyone would know if the invidia or the titek housing will bolt up to and hks 3 in downpipe? i know the invidia is a 3 in and i beleive the titek is 2.5. not to open a can of worms but i see that shearer came out with their new o2 dump but it looks very similar to the jm fab also, and the jm fab is also priced a decent less than shearer. any opinions on that?

 

If it uses the donut gasket it will fit.

 

awesome, thanks for your help. the guy i bought the downpipe from said it would fit the stock o2 housing so i would figure that it would fit the aftermarket housings as well.
