Exhaust radii... MR SVA friendly





Also posted this on wscc but I reckon you guys are a bit more resourceful on here...

I am having some problems with my Dunnell silencer (2nd hand). There are radii on it which I believe Mr SVA won't like.

Anyone have any suggestions of what can be done?

The exit is also a problem but I have put on section of copper pipe to cover it. Anyone reckon I'll get away with this?

Cheers

What size exit is it? You can buy stainless steel rings from chandlers online in various diameters.

This is what I did with mine.

2inch 90 degree stainless bend with a 6mm thick 2inch diameter stainless ring.






They fit together very well on their own.



I fully welded round the join. I wont show you a pic of the weld as it was fairly appalling. First time with stainless and pure argon and I can only weld in straight or wavey lines and not circles .

I then ground down the edges and polished up. Since this pic I have another stab at polishing and making the inside edge a little more circular. Stainless is so hard though to polish and shape. Ally is much easier.






Could you make a cone out of steel or ally for the other end of the silencer to cover those strips? My R1 bike can has a cone made of ally that covers all the ugly gubbins like that.
