pro circuit headpipe

[hondariderx]

is the procircuit headpipe worth the$? im running a procircuit silencer, 170 main, removed choke plate, removed airbox lid, k&n filter. im curious if the power increase is worth the $280? has anyone tried with good luck?
thanx

What do you ride? 400ex maybe, if you are going to do more engine mods such as a cam, piston, big bore, ect. then it will be worth it. If you are going to stay relatively stock then I don't think that it will be worth $280. If you ride a 300ex then yeah it would be worth it.

:rolleyes: i guess it would help to say my machine is a 01' 400ex huh?

what is your elevation.

i have an 01' with T-4, K&N, removed lid and choke, and im running a 160 dynojet and a 42 pilot. im at about 750 ft.

I kinda dout that its worth $280 but what the head pipe will give you is a definite tourque increase. The silencer alone basically just adds a slight bit more hp and lets the motor rev faster. Just my 2cents.
