So after looking at a bunch of website, DRD does not make a slip on pipe for 08 yz450f. I'm guessing it hast to do with the header pipe being too big.
FMF and Two brothers make a slip on but I'm worried it may not be the best option in performance and price.
I ride trail and desert. My concerns are getting better performance ( bogg ) and adding a spark arrester. I'd also like to keep the sound close to legal on the trails.
Is the drd SS/AL comp 7404 going to be best for me?
Bike is stock. after the pipe I will double check jetting. It's hard to research because the website don't have too much info. I'm not loaded with cash so I have to do my research before buying because I'll be stuck with what ever I get.
(I have heard of the 06 CDI and other upgrades but I need to start with a pipe for the sparky.)
