    I think it depends on the bike. If you have one where it all collects then it should work with one. If you have 2 it'll use 2. I think Candy has 4 and does individual cylinder tuning, though he's running 4 of the add on tuning modules to pull that off to it's kind of a nuts system, but I suppose you get the fastest, most balanced tune that way.

    The setup would have to depend on where the headers come together so it's really up to the designer.

    Hey Jay - I got an update from gofundme that included a photo of an interesting looking exhaust system. It had O2 bungs and an unexpected [At least, I didn't expect it] small diameter link-pipe between cylinder pipe merges. Is this a prototype that may be test run soon? Pass on any good news that may be percolating. Thanks.

    Awe, did that show up via FB? I went in and changed some pre sets, one was add a photo which I thought was all ready there, interesting. best be this photo aprilia-rsv4-arata-exhaust-5.jpg

    That's the Akroprovic Ti header for the RSVR. A work of art as well as functional, that secondary mid pipe helps the flow through that tight 180 degree bend plus aids in a balance of the two collectors. I had quite the chat with them boys, just couldn't get them interested making one for the VFR. Ha on a side note the work of art is only a mire $3k, but for a bike thats all ready $20K + making 190 hps, so yea...

    I'd totally be in for this if it were being done for the 6th gen - I do not own a 5th gen. :(

    ^ Figure there's a stronger market for the 6th gen has it to be available after, as LOL you know, I have a 5th gen that I can work with ;)

    well as long as the rear primary is shaped right for the bulge from the cct it can be used for for 5th and 6th gen.

    Only $3000? Well, then, as Chevy Chase said in 'Fletch', I'd better only have two...

    Just a slight up date. I had another great conversation with Gabe and introduce Miles to him, which is a fairly new owner of a 4th gen VFR. Got a chuckle a little bit here, Some people just have all the luck. He picked up knowing this VFR was a a fixer upper at a good price, while poking around he noticed that a header tube was cracked, just so happen, it's a 2 bro header WT... Yea right? Thing was, he wasn't finding any one that could repair this. I offered to let Gabe take a look, and wa-la all is good.
    In that seeing it is the genuine article, I took some comparison photos.
    Gabe now is making a wood jig, also noting some minor tweaks that could be made, but over all, he likes the layout. Now for ordering up some tubes. Then in measuring the 2bro, come to find out even though it a 4th gen header, it has 36mm id primary's, interesting, there's quite the difference. Ooo I'm liking where this is going

    Hey Jorge - I'm stoked for you and your 4 gen friend, but don't derail Gabe from our preexisting 5 gen/6 gen header project!

    Or us guys with even older bikes. Now I'm sorry I sold that 1953 Velocette. Next thing ya know, a shitload of harleydoods will want a set for their bikes. This brings up the question of being able to chrome titanium and smooth oot those welds.

    You may already know all of this, but it's very germane to this thread.

    Excellent explanation of exhaust systems.

    Yep, I've talked with guys just like him. They're all pretty much on the same page. Interesting thing about this, Gabe and I have been talking Duals, but with the SSSA it's like Huh? Maybe? Then see a left sided VFR and go Hmmm. Maybe make em like the RC51 layout high and tight, IDK. Goal is also keep it simple, but duels would be a snap to install, less hassle there merging the two. God knows all the 6th gen owners love their dual outlets even though some are single. Just more food for thought.

    Hi Jay - just checking the thread to bump it and find out if you and Gabe have any news about the headers?

    Awe.. Yes and No. while Gabe was waiting on the correct tubing to arrive for the VFR 750 2 bro header repair, he took on a Nissan R35 project, suppose to have the tubing in by now, and had it to work the kinks out of the jig and do the fix on the 750 header this next week. Thank for the poke. I Did have another chat with Mike Valasco trading ideas, so pretty excited to see this come together. This is still going to Happen.

    I'm curious as to how the 750 project now has priority, when it popped up six weeks or more after you started working on the 5 gen project with Gabe?

    Poor guy was down on his luck here local to the area where he wasn't finding anyone that knew how to work exhaust tubing, in that I introduced him to Gabe. Then found out when he brought up the header to be fixed it was a 2bro, that showed us what we need to see, it was that we found out we need 36mm tubing when it was talked about 35 being. so no biggie. it's all good for the PR. right

    Another what's happening. So it just so happened I landed a 2 Bro header for the 5th gen Wa-la, bita boom, bita bang! Wow, only took a couple years and a bit of luck and blessed timing. I should have it my hands next week. From that I'll be seeing whats the to do getting a jig made up comparing it to the stock 98-99 header. That way I'll know if I want to install this 2bro on the Viffer and run it on the Dyno. My thoughts are to still have one made up then do a comparison, now there's no guessing involved. On ward ho as they say.

    Also while at Gabes going over stuff, I lent a hand as he was working the repair on that 2 bro for the VFR750 talked about earlier, man is he good.

    I guess my question is with all of the generations and different header configurations is this going to be generation specific or as I have the 8th is it possible to fit on my and others 8th gen? I see that you are working with a 6th generation. Interest is always there but not if the end result benefits on gen over the other. let me know. Thanks
