Member Contributer jim v Posted October 15, 2018 Member Contributer Posted October 15, 2018 I went ahead and pinged BW, got the following reply - Quote Hi Jim, Thanks for your email. We do have the bike and are working on it now. The 2002-2013 is still in development, we do not have a date for the release as there is still a lot of R&D to be done. Best regards Lincoln Quote
Member Contributer adkfinn Posted October 16, 2018 Member Contributer Posted October 16, 2018 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. 1 Quote

I would hope their "R&D" has included back-to-back dyno runs against the (hopefully) 98-99 catless header, so there is empirical evidence of any claimed power/torque increases. "If" there are reasonable gains, and "if" the header is demonstrably lighter than OEM, I could be talked into a set. Quote
Member Contributer kave Posted October 16, 2018 Member Contributer Posted October 16, 2018 Holy smokes, this is looking good. I will be buying one as soon as it is released, getting it ceramic coated and will Dyno this beauty. Quote

Member Contributer Stray Posted October 23, 2018 Member Contributer Posted October 23, 2018 Just saw this on eBay: https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F382587019138 Looks like Lextek are on the game too. I believe they are a Chinese outfit but make decent end cans (almost as good as Akrapovic but not quite, according to online reviews). I like the collector but downpipes look a bit square from the mandrel. No idea what size the tubes are but they don’t look thin. Stray Quote
RVFR Posted October 23, 2018 Author Posted October 23, 2018 Ya know, that ain't a half bad looking system, way better than what's coming out over in Europe by what I've seen. Had I need one, I'd jump on this, if ,one they can be trusted to get it here. Looking at the bends and welds, then how they did the rear collector tubes, very interesting. then look at how they increased the size of the tubes. IMO this was thought out and look to be better than decent. Question now is, who's buying one? They also state what years, LOL 97 is a 4th gen, 02 is a 6th, doh....But have O2 ports. No Cat... If one is needing a header, one should seriously be thinking about this one, and at a price that seems way reasonable. again who's game. Nice find Stray . Quote
Member Contributer VFROZ Posted October 23, 2018 Member Contributer Posted October 23, 2018 The only problem I see with them pipes is that they pair the two rear and the two front. Very different to stock 5G two right and two left pairs. Tube size looks to be larger and well made. Quote
Airisom Posted October 23, 2018 Posted October 23, 2018 Looks like Lextek doesn't ship to the usa. Too bad. Guess I'll wait for BW's header, but that Lextek one does look nice though. Quote

Very different to stock 5G two right and two left pairs. Tube size looks to be larger and well made. VFROZ, I’m not a fluid dynamics expert so I ask out of pure curiosity: does it matter which downpipes are linked together? I know it’s best to alternate the pulses at the link (you don’t want both pulses getting to the link at the same time as they’d collide and impede flow) but is there a reason to pair left and right rather than front and back? I believe the best way to achieve smooth linking is to make one pipe slightly longer than the other so the pulses enter the link at different times, although you also need to consider firing order too. Thats why race headers have some downpipes with more severe curls than others - the really curly one is the longer downpipe. If you’re trimming air/fuel mixture with an O2 sensor for each bank of cylinders then splitting front and rear is best as I believe the rear cylinders run richer than the front. On OEM pipes the O2 sensor is picking up a mix of rich rear and lean front cylinder. On the Lextek your O2 sensor only picks up the two rich rear cylinders or two lean front cylinders. The Lextek gives better scope for tuning, no? On the other hand the stock ECU probably only has a single stoich setting. So getting one lean reading sensor (front) and one rich reading sensor (rear) will drive it mad. Conclusion: if you’re running a fuelling module (Rapid Bike, PC or Bazzaz, for instance) with per-cylinder tuning then you want a front/back split header. If you’re running the OEM system with two probes then you want the more balanced left/right split header. Have I messed this theory up? Does anything I say make sense any more? Again, please forgive my ignorance - I’m genuinely curious. Stray Quote

Must have been one of the first off the production line (Irish import I think, as it came in KPH rather than MPH). Do do you think it looks better than Delkevic? There’s a Motad system on eBay too. These are no longer made as company went bust. Quote

RVFR Posted October 23, 2018 Author Posted October 23, 2018 Yes.. But looks are subjective.. jury is still out, but will say there's more thought in this one, so did they do us right? That still needs to be answered. Awe, my Viffer was built 11/97 , My 4th gen was built 04/97 Quote
Member Contributer VFROZ Posted October 24, 2018 Member Contributer Posted October 24, 2018 I have noticed that all the performance headers for the Tuono V4 are set up the same, including the Akra. Quote
WackenSS Posted October 25, 2018 Posted October 25, 2018 Anyone with the know how who want to take lead on this possibility? Exhaust are not my area of expertise, neither is English! Edit: Yes I have made contact with the shop manager, and yes they where interested. Stumbled upon this company on one of the engine tuning places I spend my lazy days on Facebook. The pics attached is what he sent me, proving quality of work, was built for a Ducati 888. I think he can end our never ending headers project, and for the guys focusing on weights, they do titanium and inconel as well... As always, these nice things never gets produced in my backyard (Norway) but I suspect there are some UK guys her as well. Had I been in England I'd sure put my bike with him this winter!

LouisWhiteCSK Posted October 25, 2018 Posted October 25, 2018 We're definitely happy to help you guys out with this and try get some performance headers made up. Sorry for being lazy and not reading through the thread to get caught up (don't have the time). If you would like us to develop some headers we would need a bike to develop on ideally and the specs you guys think will produce the best figures.

Stray Although it looks nice, gonna remain skeptical on this one till I see borescope pics of the merge. The reason the SBS headers were crap is they had a merge like that, but the tube was cut and fit over a roughly cut hole that was severely undersize vs a quality, fit-for-flow merge. 1 Quote

Come now, you don't want to spend twice the value of the bike getting it there? 😉 It is for our UK friends to step up on that one. Quote
