I just purchased a used titanium muffler and there are no markings to identify the manufacturer. Just wondering if anyone out there has an idea, I would like to satisfy my curiosity!

 

I believe it is a first gen Greddy Ti exhaust before they went to the rolled out exhaust tip on the 2nd gen one.

I have seen this exhaust with unrolled tip and rolled out tip.
I have seen it with a separate stainless slip on midpipe to catback flange section or the Ti pipe welded right to the flange like yours.
I have seen this exhaust with the Ti pipe's exhaust hanger welded to the pipe (wonder if they cheaped out and went to SS pipe at this point) or a slip on hanger on the pipe like the canister's (as I presume yours had at one point).

Also note, it ooks very similar to Magnaflow Ti (made in Japan) except, the Magnaflow has a single bend in the main pipe with different placement as opposed to the Greddy which has a bend in the middle of the main pipe and one right as it enters the muffler.

there definately similarities, maybe it's a one off
