compensate for my low end

[taylorman08]

hi, i'm going to purchase a curtis sparks exhaust for my stock 400ex and some told me that the x6 was really better than the x4 in mid and top, but i will lose some low end over stock... Could i bought this one and compensate with something else like low end cams or something else or it would be a better idea to dont think about it and buy the x4?? thanks!

if you want low end power, you can either buy the x-4 or buy the x-6 and get a higher compression piston. my friend actually just got an x-4 on his mildly built motor and he said the power was better with the x-4 than his big gun from lowend to top end. however, the x-6's are suppose to open the bike up more when you build your bike.

Id suggest the X-6 with a stage one Hotcam;)
