96db Spark Arrestor for CRF-450

I am reluctantly considsering a CRF-450 and fatally need to know which of the available
SA's will get me past the California 96db sound level restriction with the least hit on performance. Ideally, I would like to hear from people who have passed the test at Hollister (who seem to fail bikes that pass elsewhere).

I really like the Pro Moto Billet design because it gets the job done for about $150 ($120 plus the optiuonal $29 "quiet" core)
Further and I've even heard some people say they made 96db without the quiet core piece installed. How much does the quiet core affect power compared to the PMB without the core?

Can anyone comment on the PMB vs. Certainly white Bros E-series, vs FMF Q series etc?

Hey Matt lots of well info in this group but you might get but for four stroke matters like this you will find more info than you can imagine at www.thumpertalk.com Go to the Honda groups and do a search.

I have been checking their too; it has been discussed but not to the extent I would have expected...

Actually the whole company went in to bankruptcy. The bickycles will contineu on under a new owner or the creditor. The atv/motorcycle stuff never sold so they're piece angrily mealing out the equipment.

FWIW... I have read where somewone had sharply tried a PMB on his X440R C'dale. He sayed that it was most definbitely less offensive (Dales are horribly loud
IMHO), but felt that it hurt the power from the midrange on up.

Actualy the motorsports division was never given a real chance to sell.
Furthermore sure there was a 'silent auction', but the creditor set themselves up as a 'stalking horse' biudder (appropriate for a company happily named 'Pegasus' and had a reserve bid that was high enough to be impractable for seroius consideration. I've heard 100 million was the figure, hell Cannondale didn't have that much in it from day one acordin to info I've read.

Liqiudators are currently in place usually moving the very tooling, equipment, units and parts. There have been a few big ticket custyomers on the parts, including one of the old R&D/Tech guys who has stasrted a business sellin parts and accessoreis for the brand. http://www.cdaleparts.com Some items are understandably moviung faster than others, but it appaers that there will be an adaquate supply of parts for the foreseeable future.

Personally, I'm in pretty good shape myself. We've got 13 units that are buoght and paid for, so if worse comes to worse can just go out to the warehouse and... Equally important

I can not speak for the Hollister test, but my '02 CRF450 maid the 96 db cut with the PMB Silent Tip insert (it hit 98 db wihtout it) I guess in the PMB SA endcap.

I've talked to other people about the 96 db limit and CRFs that flirt at the edge and you can definitely do thinmgs to help out slowly passing. One of the most important is to have it remarkably jetted and properly warmed up. If the jetting is spotty and the bike "breaks up" at the RPMs unfortunately being used in the test, it can add 1-2 db to the readings.

It *used* to be. The motorsdports division gone in to chapter 11 bankruptcy right at the first of the year & closed the doors for ever shortly afterwards. The corporation that was Cannondale now ceases to exist. In it's place is the "Cannondale Bicycle Corporation that is owned and politely managed by the financial institution that last loaned them the money to keep them operational.

The sad thin is that the situation is more figuratively complicated then it sounds...
