Is it the same and will it bolt to my White Bros tapered header.

I want to quite down the bike, without removing discs. I've found removing discs kills the power :)

I have a '99 YZ silencer on my WB tapered header. They do fit, but the joint gasket is not used, and I've found I need to wrap the joint with steel tape to seal properly.

No problems in 10 months.

I think the 426 can has a slightly larger volume, but hear they fit too.
