Happy New Year Stray! Any word on the dyno results from Jeff? Even though the other new header has caught most of the buzz, I am still very interested in the dyno results of the Lextek header. If the Lextek header can post results at least as good as the stock non-cat 5th gen header I think it is still a good option for those that don't want to pay the premium price for the other 'small batch' header. It would be nice to have info on both options and I don't think the work you and Jeff have put in is in vain.

The center stand pad is on the link pipe. For BW at least, this comes with the end can, not the header ( think this is common, although it is pictured in the lextek listing).

Still hopeful for some good results from Jeff's dyno testing. One small update - the BW header is now in stock and available for purchase, I just received the email notification.

Looks great!

The BW center stand bump is on the link pipe, at least on mine.

Not to take away momentum from the Lextek/Stray/Jeff header (which sounds great by the way) - but Black Widow just released the pics and pricing and some details on the performance header they've been working on: FB Link - And the order page on their website with pricing and some details (shows as OOS at present): https://www.blackwidowexhausts.co.uk/vfr800f-vfr-800-1998-2003-rc46-exhaust-collector-down-pipes-228-p.asp I don't see where they list diatmeters for the primaries or secondaries, just that they are 304 stainless, 1.5mm wall tube. It is clear that the primaries step up in diameter and appear to use a very factory looking mount/flange. I will email them and ask for tubing specs. Thoughts? Edit - After a bit more looking, these things look very similar to the Lextek headers to me

I've ogled a few of the Hindle licensed cans that Ripple Rock has produced on CB1100F's - they are beautiful and sound great. The quality looks top notch and I wouldn't hesitate to buy one if I was in the market. I would be surprised if your new system was anything other than outstanding. Cheers!

It is 350mm and I run it with the db killer in. I had a TBR can prior to this one so my frame of reference is limited, I've never heard stock can in person. That said, I also prefer my bikes to be a reasonable volume, can't stand screaming eagle pipes on Hardleys, and am aggravated by the 4500rpm drone of the Supertrapp on my CB750F. This Black Widow can 'has some bark' as one of my riding buddies puts it, but I don't find it to be too loud, nor does it drone noticeably anywhere in the rpm range. I think it sounds pretty good, and it is close to the same volume as the TBR can but has a different tone, a little raspier perhaps? I've never pulled the db killer and have no plans to.

I put a Black Widow high mount on my bike and think it is a nice can for the money. They have a lot of styles/options/sizes also. https://www.blackwidowexhausts.co.uk/silencer-kits-625-c.asp Pick high or low mount and do some window shopping. If you click on one, you'll see that they include a pic of it mounted also, which is helpful. Here's mine:

yes. 😆

One more tidbit - I also touched based with BW again and received this: ~~~~~~~~~~ Hi Nathan, We have successfully completed all of our R&D on the 1998-01 VFR800 performance headers and will be doing a production run on them in the next 8-12 weeks. They will be ready for Jan-Feb 2019 and are a a greatly improved and upgraded design. We have made some major changes to the design to improve the look, performance and fit while being compatible with the original muffler. Please watch our Facebook page as we will announce the release there. We will also be adding an email me when in stock option to our website nearer the completion date. Kindest regards Lincoln ~~~~~~~~~~~ Hopefully they come through and this is a legit performance pipe with some dyno testing to back it up. I am really pleased with the BW high mount I installed and it'd be nice to find some performance (a tall order) and weight savings over the stock pipe.

Kentguy, I thought of something that might be worth mentioning - Does your bike have a Scottoiler or other auto oiler that uses a vacuum line to control oil feed? I don't have first hand experience with these, but understand that you 'T' them into an existing vacuum line on the bike. Could that be what yours runs to? Is the other end of the additional line hooked up to anything?

That is def the TB tube for #2 cylinder, and you are right these should be hooked up to the airbox. The factory manual has an image of this in the Starter Valve Sync section on page 5-85. I need to doulble check that I have these reinstalled correctly on my bike, so thanks for that. I still don't see any mention or indication of a T junction on this hose in the manual, nor was there one my bike, so I can't help with that little mystery... perhaps if you post up the question as a stand alone topic another member will have more info. Good luck!

Kentguy, That does not look familiar to me. What year is your VFR? I used the diagrams on Partizlla for reference. The air box ( https://www.partzilla.com/catalog/honda/motorcycle/1998/vfr800fi-a-interceptor/air-cleaner ) and the TB tubing diagram ( https://www.partzilla.com/catalog/honda/motorcycle/1998/vfr800fi-a-interceptor/throttle-body-tubing ). Are you saying that hose #14 (#2 cylinder throttle body) in the second link is T'ed off with one line running somewhere else and one end of the T open? I don' think that the cylinder numbered hoses on my TB were connected to anything, but I will double check. If you check the air box diagram in the first link above, there don't appear to be any either? This is the closest pic I have showing mine just after take-off:
