CRD quiet exhaust

I've heard the "uncorked" WR's in my riding area and I know you guys need some help finding a good pipe that doesn't kill the power!
Sorry I tried not to give any digs !

Have you had your CRD sound checked using SAE J-1287? (The 20" test at a 45 degree angle) We're hearing that the 96dB pipe will really test at 94dB for sound check purposes, but don;t want to buy the pipe and have it fail. The XR400 in the CCC test (December 2002 issue of Trailrider) was using the 91 dB pipe, which is um... HUGE. Looks like a torpedo under your fender.
I'm leaning strongly towards CRD since I have a dealer 10 miles from my house and they look high quality.

over the thanksgiving weekend.
Ranger Matt said it could be a 50/50 pass fail pipe.
I would not call it a 94db pipe on the wr.

Have you had your CRD pipe apart? I'm curious if it's just an oversized version of a regular perforated center pipe, fiberglass packing plus outer can silencer like those used on pretty much every motocross bike ever made. Or, is there some internal baffles etc? If you've ever had a chance to look at the quiet version I'd also be interested in whatever you may have seen regarding it's internal design.

I noticed your quote "Way better low and mid than stock uncorked and only 96db's" Are you being honest for real deal holyfield? Cross your heart hope to die serious? Seriously though, I was looking at that pipe. Until I saw the 91db version on a YZF426 and didn't like how freakin long it was. Almost went to the end of the fender. Looked vulnerable to any slide outs or lay downs. Is the 96db version as long? Have any pictures of it mounted on your bike?

The low end and mid range is not as bright as the arrow I was using or an uncorked stock pipe. The top end feels very similiar to those other pipes though. Will have to wait for the next dyno session to know for sure what is really happening.
