It's possible your Greddy Ti catback is 80mm (~3.15") I know my Trust Ti catback is 80mm and the piping was indeed larger than the UR testpipe.
The STM unit is a nice piece, the flanges are SS and chunky. Not as chunky as the flanges Buschur uses but still very heavy duty. You'll have to use an 02 extender though as there is no provisioned mechanical o2 fix (just a bung welded in). Good luck dude!

I dont know where the bolt holes are for reference but when you mount an o2 bung it should be in the 10-2 o'clockish position, If it's on the bottom (where it would be easy to access) the sensor could be contaminated with moisture/condensation and such, so they say. If all the car engineers designed it that way I'm sure they did it for a reason too.

Its a straight stainless steel pipe, 3" in diameter, has flanges on both ends... with an 02 port.... does it fit? if the answer is yes, why does it matter which one you go with besides cost? (cost is why you buy things used)
I'm just curious on how a very simple piece of equiptment causes so much consideration

Question. What are you exactly considering between your choices?

Why is it with you Newbs on this forum , you always seem to have a smart *** comment???
well obviously some are made better then others.... some are ACTUAL 3 inch in diameter and some claim to be but are really not. as well as some only work with their own brand... thats why im asking, damn near every company makes a test pipe for an evolution, but like everything else you want to review a product of its quality before you buy it no ???

b) I'm not a noob
It was an honest question because the product is very very simple. If you have a ACTUAL 3in pipe and decent welds, there are no benefits between ANY.... Normally such consideration is put forth on more technical parts
a pipe is a pipe, simple as that. it's not hard for anyone to make a circle-weld with a machine.
pretty much any place you buy this from will function just fine, especially if it doesn't see snow/salt in the winter

well if i recall correctly i ordered a 3 inch test pipe from UR years back.... and now that i current changed my setup to a greddy TI cat back with some heavy duty downpipe, not sure of brand because my buddy whom i bought it from forgot the make, all i know is that its a heavy well made piece, the down pipe which is 3 inches is larger then the testpipe, so its not exactly a perfect flow and its causeing somewhat of an exhaust leak. how do you feel about the STM TP? is is good quality and does it have the 02 bung ?
I have a Greddy TI exhaust mated to a STM test pipe. It's a full 3 inch testpipe and it's very good quality.

If you dont like the thread simply dont comment
thats good hear i think i might look into an STM TP, so everything fits and performs good no problems ? was the 02 sensor easily able to connect to the 02 bung?
Hey.
After seeing this thread, I measured a one of our STM Stainless Test Pipes last week before shipping one out.
The inside diameter of the Test Pipe was just slightly over 2 and 7/8th inches. Almost 3" but not 100% there.
