I'm picking a 5th Gen today that has a stainless header and a TBR slip on. Anyone know if the original TBR header is marked to identify it as a TBR system?

If it was a full TBR system the seller would have bragged about it. The TBR header will discharge from a slightly different location so the mid-pipe needs to be different... it wouldn't be a standard slip-on that fits the OEM discharge location. Measure the primary pipe diameters and post a few pics... owners of TBR systems will be able to spot if it is the real deal.

The Two Brothers header is pretty easy to eye ball as it has spring loaded slip joints.


Never mind, the newer delkivics are using springs now too. Here is your header:

Hi there,
anybody here?
Guys, I very need photos or size (аpproximate dimensions, angles, distance between them) for back downpipes of TBR Headers (or Erion)
Thank you in advance

p.s. I bought TBR headers, but with out back pipes, and now I have the opportunity to make them and I need some sizes :)

You'd probably have better luck replicating the rear downpipes from the original header, to match up to the TBR. That pic is of my header but I can't get dimensions off the bike right now. I can send some pics if needed, IM me.

That's...corrupting.  There are just so many things I would do for that... :blush:

 

Ciao,

Came across your posts on exhaust and thought you might all like to see one of these for a 98 vfr800

Who made those? Can another set be built/purchased?

I built that exhaust up a few years ago now. I race a vfr800 in the UK. It is running an long stroke 360 crank now and a different exhaust to suit. I might sell that one in the picture if someone is interested. I can make another one out of 0.9mm stainless or 1mm titanium though. The ideal sizes I have calculated are available in stainless but there is a compromise in titanium which is not good. That VFR exhaust was on tuned engine and I designed it to suit the cams which takes the revs to 14K so it may not suit a road bike. The VFR engine made a good 142hp with that exhaust but as I mentioned, it may well turn a road bike very sluggish

You are not the first and won't be the last to dangle the potential of a full system in front of the vfr community.  There is a good amount of interest to buy in say the $600-800 range, and some interest to sell in the $2000+ custom one-off range (if you can even find someone willing). 

 

If you want to gauge interest, you need only to look at the first page of this thread and this post from April in the other VFR header thread:
http://www.vfrdiscussion.com/index.php?/forums/topic/85354-5th-6th-vfr-800-header-build/&do=findComment&comment=1060365

 

The specifics required by the group have mostly been worked out, if you read the rest that thread.  Up until now, there aren't many that have built the full system from scratch, so you are ahead of the game in that regard.  The real market seems to be in the 6th and 8th gen bikes, so if you want to produce a bunch of them, they must fit on those generations.

I likie this,  Very interesting to say the least. As most know, I'm on the path to replicating the Two bro  that was available back in like around 2000 now that I know what it really does. I've done all the tune and what not with my 5th gen, it's a pretty good up grade.  Like you,  there are trade offs, luckily not much from making the VFR not  road worthy.  I'd say header interest wise there's a 4-1 ratio that want em for their 6th gen vs. 5th , makes sense since there's more of those running around, That has me looking for that loaner 6th gen and run it on the dyno for a know the facts,  only thing getting in the way is the shop is moving, and it's looking to be a $1000+ ea. if,   But hey,  it's all good.   I like what you've done,  be fun to read about the 142hp and how you got there ;)  and what the draw backs could be.   Carry on

Ok, thanks I will aim to finish the website and publish details to such forums as you mentioned. I am looking to focus on the specialist smaller quantity items. The exhausts take weeks to make by hand so they do not lend well to mass manufacture. Also I am not too keen on making simple 4-1 systems just to make some money. I like to focus on the more artistic systems.

The website will be mainly focused on the bike itself and tracking the project working towards riding at the TT. I have been racing it on smaller road races in Ireland and the isle of man to iron out the problems (which there are many)

It is my own chassis, double wishbone front end. All bodywork, tank, electrics, throttle bodies all made by me. It's making 152hp now with peak power at 13,800 but still a long way to go before being competitive against new machinery.

I will let you know when it's done, but to all the VFR fans, there is not much left i'm afraid; only the original crankcases and heads are from a 1998 vfr800, pretty much all the internals are my own design

I tip my hat to you sir. 

That looks bloody awesome. Nothing like a VFR, but awesome. 

I would hate to think what it all cost.
