Hmmm... ok. Then the FSW is not an option But you're saying the fmf headers WOULD fit the DG-O, but it would still rob me of power? ***confused***

 

The DG-O and DG-R will NOT fit the bell of the FMF headers. The DG nipples are far too small. If you wrap a whole roll of header wrap around the DG nipples, you can get them to seal somewhat in a FMF header and will be rewarded with a nice power loss everywhere.

 

Bummer

 

KLXster, if I get it I'm half tempted to let you borrow it. Your help (and many others) and research has been invaluable.

 

Well, if you get it, we'll do measurements for a "best guess" CVK setup.

I've blown up your pic - I really like the system. That apparently "robust" heat shield means they went the extra mile to provide a fully engineered system for their customers.

They appear to have employed a simple revamp/recalculation of pipe size (O.D./I.D.) - no other "interesting" design features are apparent. This approach is just fine, it's "low tech" but it's also an old and established method of tuning power curves with solid math backed up with many decades of practical application verification. They have likely chosen a size that enhances power in the upper 1/2 of the RPM range - but I won't know until I have the detailed measurements.

You might check around for a Dyno shop that'll give your bike a quick run for under $60 - for AFR,TRQ,HP charts..
