Ordered a gnarly pipe -jetting?

[NJGregsCR]

'97 CR250R is currently set up with FMF Fatty, FWWeight, 51 tooth rear, steel clutch, ProCircuit Nature Friendly silencer & DB Snorkel.
Bike runs and starts great, and if spooge is an indication it's jetted rich- but runs great.

My question is, I just ordered an FMF Gnarly to continue my focus of lowend torque for tight woods riding. Will this pipe addition force me to rejet?

Check the FMF website, they offer jetting suggestions for a number of bikes when using their pipes. When I bought my Gnarly pipe it came with a paper offering jetting suggestions as well.
