[raptor350yfm]

I have a 07 raptor 350 with a mod quad air intake adapter with K&N filter. im lookin to compete with a 400 ex and a ltz 400. I want to know what's good exhaust kit(thats affordable) 4 hundred tops. and i was thinkin bout that edelbrock carb as well. will these mods be enough to take on those 2 bikes? If u have any other suggestions please post. i need help. their r just 2 many exaust systems outheir to decide from.
Thanks in advance

i have an idea how does it sound... FMF Powercore 4 and a edelbrock carb. will this give me the power i need to compete

HMF is the best bang for your buck on the exhaust.
If you want to keep up with ex's and z's you will have to get into the motor pretty heavy.

there's no replacement for displacement. You'd save money by selling your warrior and buying a suzuki 400.
