I've seen that happen on a Cannondale before --- in that case, the rider hit the revlimiter - which is only an ignition cut on the CDale (still dumps raw fuel into the chamber).
As it skipped thru the limiter, it backfired blowing the silencer clean off & tearing the header off about midway. Ruined the whole pipe.
Pretty crazy - but it happened.... I would have figured it would have separated at the joint first.
Well then, he just needs to ride faster :cool:
If it were me, I'd rather have the story told that I was hammering on the rev-limit than taking it in the rear :eek2:
Lmao:D

I shot you twice.:cool:
I will check all of the official testing guidlines and report them here. I am not officially the sound test guy at work but I sit right next to him. I will send him an e-mail (I am currently stuck in Japan testing for Honda) and ask him for all the official factory testing method for exhaust noise.Quote:

Gentlemen,
Here is a little info on you for sound testing. I am an engineer and I know that thier equipment is bogus. They cannot accurately measure the dBs with their equipment. Yeah their method is somewhat correct but their area & equipment is not. They need to have a calibrated sound tester (I don't think theirs is) because if they can't calibrate it then how do they know for sure it is reading what it is. Also they have to do the test in a sound proof area. The best is an anecoic chamber (Sound proof room - no echos). If there is any other equipment or quads around it will cause your results to be higher. Also, if it is windy it will cause the readings to be higher by affecting the microphone. Please use this as defense the next time they say you busted their limit.
Actually, I have a great idea. I will measure my 450R just before the next GNCC at work with proper equipment. Record the data and take it with me to the race. If they say that my blows the limit but passed at work I will call them out on it. (I have yet to have my 450 checked - missed last 3 races).
Hope this helps all.

I was told my pipe was 108db. I then asked to see what the meter was reading away from the quad...93 db. Is the 93db considered a sound proof area. According to RP, my pipe had to be within a percentage of the surrounding area. Does anyone know what that % might be?
Also, I know a guy that measured 105.2 on Friday paid his $25 to have it repacked (which never happened because they couldn't remove the insert) and went through tech again. Keep in mind he was given the packing to re-pack the pipe @ home. He teched @ 103 db. The guy with the meter was boasting on how much the repacking works.
RP has some serious issues that need to be addressed regarding this.
Thats not it at all, That pipe only has 3 races on it. The silincer has two mounting points and even if it was that, those mounting points would have to move to put any stress on the header.Quote:
