Do i need to jet for a slip on?

[Tocco]

I am looking at getting a FMF powercore 2 for my blaster, my header pipe would still be stock, but would i need to jet for a stock header and that fmf slip on? Thanks!

No

You shouldnt have to, but I would check. It never hurts to check

I'm gonna say yes. Better safe than sorry. Plug chop to confirm!

It is not usually needed to re-jet for an aftermarket silencer fitted onto a stock header pipe.

It could be an opportunity for you to check your engine for correct jetting, if you are in any doubt by performing a plug chop.
