Changing 4 into 1 to 4 into 2 exhaust

[Razor]

Haven’t attempted it, but it’s on my list. I’ve got a Yoshimura system, and thought it would be cool to have dual exhausts. Only thing holding me back is I’d loose the center stand.

Exhaust tubing can be purchased from various vendors on-line. You can order pretty much any size tubing and angles to suit your needs.

Edit, just saw Nortoon’s response. Wow!
On the other hand; anything custom/handmade will require the proper equipment and skills. If you let someone else do the custom work, you’ll likely spend as much or more. Doubt you’ll find a used dual system, but it doesn’t hurt to look or ask
