Does anybody know how many db's an hmf exhaust puts out. i know there are different ways of testing and other factors besides exhaust but i was reading on atvscene where it was said there will be a new 99db limit next year. this has got me a little worried. i dont want to have to go back to a stock pipe and have a slow bike?!?

The DRD only puts out 96Db. They claim 6hp and 20 ft. lbs. of torque and that's just a slip on.
the TC, sparks, and ESR are the top 3 pipes IMO and theyre all over 99db :evil

Sounds like they better start working on quieting them down then.  I think it's a lame rule, but it kind of makes sense.
How does it make sense for closed course competion?

I agree, that is stupid rule. I just got my hmf slip on, and there is no way i'm putting the stocker back on. Does anybody know the hmf's db level. Dirt Wheels said that the hmf z400 exhaust is 98 db in the march 03 issue. So maybe us HMFers will get lucky and the yfz's won't be over 99 db.

Stop crying. A properly modded stocker will compete with an aftermarket. And the sound is like 7db less.
not flaming man, but you wanna give me my $500 back from my pipe i bought?

that rule is crap
