300ex exhaust and jet questions

I've been thinkin about putting on a white bros. e-series silencer and same brand head pipe on my 300.Stock except for the white bros. air filter.Does the head pipe really make that much of a difference? I've heard yes and no.Also what would I have to do with the jetting.Would this help my cold starting problems?Thanks for any help.

I would get the head pipe. It will make a difference. I would put about a 130 main jet in.

I have a FMF Megamax 2 complete system with a K&N filter closed lid on my 300ex and all I did was move the clip on my needle up 2 noches and it is running great.

i would get a lrd or ct race exhaust they are both much better but with power comes the loud bark of a 4-stroke what a beutiful sound. well anyway if you cant get them get the whitebrothers pro meg silencerand oversized head pipe it's well worth it to purchase the two together as a package. GOOD LUCK!
