I own a 400ex and plan to add a pipe right now and in the future add a 416 and cam. The question I have is what exhust would be a good idea for the future mods and should I go with a full system??? Hey Gabe: how is your quad running?? what pipe do you think?

 

Usually when you buy a hop up kit such as the 416 or 440, the manufacturer of the kit recommends or even includes a pipe and silencer with their kit.

 

If you dont care about alot of noise, a SParks X-4 or X-6 would be good choices. They both flow extremely well. I had an X-4 on a stock motor and soon I will have an X-6 with a highly modified 440 motor.
