i was wondering is there any performance to gain from upgrading to an aftermarket header?
i know it would be handy to not have to unbolt it to change/clean the filter
also those torque stuffer things u put inside the start of ur header, anyone used one or are they just cheese?
thanks - Brett

My guess would be yes, (maybe very small gain over the stocker) provided it was matched to a silencer and intake and jetting were matched as well. The header alone? I would guess little or no gain, possibly worse if not re jetted. HOWEVER, I don't have a 99 WR400 or even an aftermarket header on my 03 WR450, so the validity of what I say could be nill. Just this motorheads' opinion.
