View Full Version : ST165 Downpipe

09-10-2011, 09:54 PM
In the unlikely event anyone actually has one for sale I am asking it here.

I could use a downpipe that has a bung for an O2 sensor with the 5 bolt flat ST16X flange on it. Anybody got anything even remotely like that?

PM me if you have it - I would like it to keep this T3 Turbo on the 1st GEN 3SGE I have to put int my GTS this winter - I need a downpipe of any sort - the turbo has a flange for the ST-165 type exhaust and I need something for the O2 sensor and the external wastegate dump - all I have now is a pipe that stubs out right against the oil pan.

I'd like to try to bring the thing up with this turbo that came with it - else I will just need to get a stock exhaust manifold for it, gutted CAT or not, and bring it up NA to prove out the engine.

Another question - i any has the time or knowledge - would a 4th Gen header physically fit a 3SGE in a 5th gen body? Do Ya' think?
