400ex Full Exhaust

[FoxMxRiders]

I want some information about some full pipe for a 400ex.Now I have a white brother R4 slipon but want to change for a full pipe if I can find good one.

I want a pipe that a quietcore is available and with the quietcore,I want that the pipe will sound near stock one.I know that is crazy but need a quietcore.

I was thinking about the Yoshimura Rs3 or the HMF Full.But I don't think that Sparks do quietcore for there X-6 exhaust.

What pipe do you recommend to me that will be quiet with a quietcore.IF you know the Dbs that will be appreciate.

Thanks

ct makes alot more power than most pipes and u can change the noise out put by taking rid of disks

witha yoshi u can buy a TEC kit which is 2 different inserts, one is like 98dbs and the other is like 93, and they claim u still get 95% of the power gains

the hmf is a great pipe but it may be a little to loud for what you want even though it has a quiet core avaliable.
