Exhaust bore size?

[106diablogti]

I have a Magnex middle section for my Willy and have a quick question, will I have to get a reducer sleeve to mate it with my standard williams back box or is the bore size the same?

Thanks

Rich

I would have thought the bore size would be the same , but may be wrong
I have a Magnex system and the bore size is 2 inch or 51 mm ...

Cant seem the willy exhaust being smaller than 51mm bore ..

Magnex on mine is only 2" but it is on a Valver so that probably why ..
