If i just put on 2 silencer and no pipes will i still have to re jet? ( 2 power core 2)

 

You said top end HP so go with CPI inframes.Advance your timing 4-5 degrees,rejet and by clamp on air filters.Get a set of 8 paddle 22 inch haulers.When you get ready for portwork you'll already have the perfect pipe.CPI's love portwork.BTW get a 13 tooth front sprocket so you can launch in second.
