I want to set my 450R up for motocross, and i was wondering what the best motocross exhasut is for a 05 450R?.....I do not plan on buying the full system right now, all i want is a slip-on....Thanks

Also is there any other cheep little mods i can do to help it alittle?

 

My friend who races has the sparks racing system. I really like it.

 

if your going to go with just a slip on ,,the DrD is the only way to go

 

i recommend getting a full system. You probley will regret it later if you don't. And it will cost more in the long run. I like the hmf exhuasts.

 

I have a sparks on mine and I have no complaints.

 

i would say the Fat Boy 4 pipe i have seen on TV and in the Mags that most pro racers 450r's are equiped with the fat boy 4 pipe. I run the complete system on my yfz ann rejetted with a CDI and a K&N i could really tell it awakend the motor

 

visit CTracing.com they are the best!

 

Thanks guys, i was lookin at the Dr.D and the WB MX4 slip-on, the reason for the slip-on is the lack of money and limited time before the next season starts. Thanks again

 

My brother has the MX4 slip on for his Z400 and it sounds awesome and really helped it out by opening it up. Not too loud but still you will give an ear full but it as said, it sounds good. I was actually surprised at the performance as well. I also have a bud that runs a sparks pipe on his 450r and that thing rips.
