jetting from aftermarket exhaust to stock

[quadwanter]

I was wondering if you have to change the jetting much when going from an aftermarket muffler back to the stock with the hrc cap. Also will the stock muffler fit a WB header?

no one?

If your air box lid is off, or HRC style with a stock exhaust and HRC end cap then you jetting shouldn't change much.

No idea about the stock silencer fitting the WB header. Would depend on how the mid pipe connects, and what size the tubing is, doubt it tho.
