ID this pipe

Got this pipe in a parts lot of mostly 1982 250xc stuff. No labels or numbers on it, but it's not the typical Husky stampings or tabs. And fatter in the mid-section. Tabs are in the basic 1982 locations. Asch? Displacement?

I believe that is I either a Pro Circuit or Asch pipe. I had an Ashe pipe on 79 250CR many many years ago and it looked just like that.

Thanks. I got some 430 stuff in the pile as well. I wonder if it's 250 or 430.

Looks like the 430 pipe to me. The 250 pipe stinger is smaller in diameter and at the very aft end had a collar that sized the stinger back up to fit the oem silencer. Also the rear mount bracket on the 250 pipe is welded onto the stinger due to the 250 stinger was longer than the 430 pipe's stinger.

I forgot about the stinger size. It's definitely a 430 pipe. Thanks.
