2010 yz450f aftermarket exhaust

Davey. Is it the stainless system? If so, from feel, how does the weight compare to the stock system?

with the SS Yoshimura will the performance be affected if you were to remove the insert completly?

No it will run a smidge stronger, though it will be louder. I would get the $29 insert.

Hey Dave hear that I think I need to add mrd. sponsorship to my resume!!:eek: Actually I like to encourage everyone to purchase quality products from people with excellent customer service just like MRD!

My birthdays coming up so maybe the old lady will spring for it...:banana: But I will be placing the order very soon!
