Hi guys/gals- first time posting- I'm a mazda tech of over 20 years, and I came across an old stock muffler from an early rotary mazda of some sort (rx2-rx4 possibly). The item is not in the best of condition since it has been sitting on a dusty old shelf at the dealership where I work for quite some time. It was never used. Looking for any clues as to what it might fit and thought maybe this forum could help. Also looking to get rid of it if anyone needed it. thanks in advance. Gonna try to upload the photo I took with my phone to this thread.

 

Welcome. I moved this thread to the new member technical. I will PM some people that may know what this is from as it doesnt look like an RX-7 muffler (as you thought).

 

its an old school muffler...many did and did not come with that kind of setup you have there...I know that when i had my rx2 the stock muff did look like that...

Also on some 79's not all but some the did come with a style like the one shown above...

 

Looks RX-5'ish to me. The one on my Cosmo is very similar. Is the exhaust tip a flat rectangle?

 

well you could be very correct on that, it is either for a Cosmo or Rx-4 they are very similar. Either it way it doesn't matter to me as I have a use for both

email me please as i am interested in the muffler

That is a "main muffler" assembly for an Rx-2; reference: Clymer Rx-2 & Rx-3 Shop Manual, page 86. Matches the breakdown picture exactly. The Rx-3 assembly doesn't have the small chamber in the pipe at the header end.
