Delkevic or?

With the exhausts looking too rusty to recover it looks as though we are looking at a blow to the budget.

Delkevic make replica exhausts for the Kettle, but at £1499 they are too hot for me.

However, they make expansion chambers. A 3-3 system that is about half that price in either chrome or black ceramic.

There are other makers. I almost bought Allspeed exhausts some years ago, maybe 25 (!) but didn't. Maybe I should have and kept them nice and safe!!

The prices now are very high.

Another choice might be Higgspeed.

There are so many choices and catering for many sizes of wallet.
