Pipe ID please

[mawso]

Can anyone ID this pipe. It has no stamping on it anywhere and has a TS manifold. It looks fairly old maybe early 90's ish...but who knows???

I was told it might be a track pipe...but with a TS manifold? Could it be an old Grp6 track pipe?

Measures up fairly close to PM28 dimensions around U bend and cones.

Any ideas welcomed.

It's not made by Chiselspeed anyway...already know that much.

Thanks.

swift perhaps?

Swift maybe. Thanks for replying...remember one of those from first dyno shoot out Scootering did, it was pretty good! No stamps or markings on it though to confirm, could even be home made I suppose. Best way is to give it a try on something I guess.
