[QUOTE="roundel, post: 152800, member: 18281"] I have a wr400 and was very shocked to find how noise level and performace are very closely related. With the stock WR400 exhaust it is indeed quite, but it is also way underpowered. I mean like a choked up xr250!! No kidding, no topend ! With the FMF pipe the perfomance is problably what you would expect, but now you have the noise....... A lot of poeple like you and I have this deliema. I purchsed a supertrapp "quiet system" for mine for around $200. This exhaust allows you to adjust your noise level by adding or subtracting discs. What I have found is..... It is'nt any fun to ride until the noise starts to become unacceptable. Oh well ! FMF has a new quiet system exhast that is supposed to give you both power and low sound, but the price tag was more than I was willing to pay. hope that helps [/QUOTE]
