[250x]

looks like an old DG, just don't quote me on that.

To me it looks like DG sections, the front possible an early open header, with a spark arrestor welded on. Most likely it's an RCM DG that someone shortened the silencer on to pass race inspection and ad flow.

I dont think it was welded up DG, all the weld look to even and perfect to be a home made job

The style and look of a pk racing exhaust is my guess .
