I just bought a set of maxxis all traks for my 400ex(awesome tire by the way) and need more power because it just doen't have any on the top end anymore. I am taking care of gearing as I am getting a 14 tooth front sproket. I am in a delema as weather to get a Mega Max pipe or supertrapp ids2. People tell me so many different things about these 2 pipes I don't know what to believe. Whick one is quieter? More Power? Better quality?( as in not breaking or cracking)I am already getting a K&N Power Kit.Please Help

 

If you say you don't have the topend anymore, why are you gearing it down? What you should do is put a 16 tooth front sprocket on it and then get a full pipe (mid range and all) and then it would be nice, have lots of low end with the pipe, plus a top speed that is nice with the gearing.

 

My old megamax pipe cracked in half 2 times before I got rid of it. The supertrapp would be a lot quieter then the megamax pipe, but there are so many slip-on pipes for the 400 it is all in your preference, but I wouldn't recommend the FMF. If you are looking for a quiet slip-on that still puts out power, then try the Big Gun with the quiet core installed.

 

I have a Supertrapp pipe and it works great esp in high-end power but dosnt have too much low-end power though..

 

what I meant was I lost top end POWER. in 4th and 5th, goin up hills, I go slower, need a good quality ,fairly quiet pipe that gives more power

 

did it ever have topend power?
