Loud Pipe

[MikeMan]

I have a White Brothers E-series pipe on my 2001 400 ex and it seems very loud.

Is that normal or should I repack it?

Also I am new to atv's -- I am having probs with the spark plug removal, what socket should I use? Every socket that I use seems to thick to fit in to remove the plug.

All suggestions are appreciated.

Take care, Mike.:confused:

I used a chainsaw wrench to get mine out lol. Thats the one that has a flat head screwdriver end andhas a two sided socket on the top of it. If you have a couple of them lying around or know someone that does try it cause the 400 plug is real hard to get to. I went through the same problem.

go to a local dealer or shop and buy a special socket. They fit perfectly and are made for it. that's what I did

take a few disc off then see how that works I the the more disc the louder it is and the less disc the quiter
