Like the title says Polished SS down pipe thick flanges & no fitment issues. Replace this pipe with another dp with two sensor bungs welded into it. Selling for $175 shipped. Jack https://www.nopistons.com/forums/pub...>/rolleyes.gif

My friend with 89 tii has been looking for one. But why does it have 2 02 bungs?

1 for O2 sensor and 1 for A/F gauge, or exhaust temp gauge.

What diameter is the dp?

Don't A/F gauges get the signal from the 02 sensor itself? All cars I've seen, including mine is like that. Also I'm pretty sure EGT is taken at the manifold and not DP.

Just an FYI-

Pyrometer

Another common location for mounting the probe is in the turbo down pipe. This will cause your gauge to read Turbo Outlet Temperature (TOT). TOT readings can be much lower than TIT. This and probe installation are explained more in literature that comes with each gauge.



Also,if you want to add an additional heated O2 sensor space is provided.

So sorry for not checking my post (didn't get an email notifacation) yeo 2nd bung is for EGT. I don't have a modified exhaust manifold yet so that's where it's going. The DP is a 3" and is for a 3rd gen (failed to mention that too) also since the last deal fell through I'm ready to get rid of it. $100 plus shipping. Jack

Still up for grab's offers ? ? ? ?

Anyone interested for $100 + shipping ? ? ? ? ?

the two O2 bungs are for a Wideband O2 instead of the shitty Narrowband , most commenly run on single turbo Vband downpipes, wideband = gawd
