aftermarket headpipe

[WhiteYFZ]

Hi,

I have a yfz 450 with a lrd slip on exhaust. I should have got the full system, but at the time i didnt know much about my quad. What is a good aftermarket header? Does it really make a difference? I got the bike rejetted with the pipe, but if i get a new header, will i have to re jet it again?

your going to have to rejet after you put a header on and i think lrd sells head pipes
