Turbo back exhaust question

[OnlyGoWOT]

What size bolts and how many do I need. I'm doing a new ported stock o2 housing, dp, and catback.

Didn't find anything for exhaust in there and I'm not sure if it makes a difference but I have a gsx and that's for a fwd.

Anyone?

No one knows?

It's a hard question to give a straight answer. As for bolting the sections of the exhaust together there are many different sizes of bolts that could be used. There are also many different brands of exhaust with many different designs, number of flanges and so on.

Its hard to say. I know the hangers should be 12mm. Otherwise, the flange bolts are completely up to what system you go with.

As stated before the exhaust flange bolts can vary in sizes. The o2 housing studs though Where the down pipe flange bolts to are, 12mmx1.25 pitch iirc. I believe the o2 housing to turbo hot side is also the same.
