im surprised that you couldnt find anything on the forum. im not sure if anyone makes a 2to1 exhaust that already fits on our bike. i could be wrong though, my knowledge is nothing compared to a lot of guys on here. i have seen some custom 2to1 exhaust on here before though.

I would think you could just use the existing header, it's a 2-1-2. You would just need to cut and weld a patch for whatever side you wanted to block off. If you wanted the can on the right side though, there is a restrictor in that pipe that would need to be ground out. The blockage is near where the red line is in the photo.

Nobody makes a 2-1 for the Superhawk... So your only option is custom...
Several members have attempted it and you certainly need a re-jet to make it work... The reason being that you loose midrange grunt and gain top-end...

It's cheaper and easier to drop $500 bucks on a decent set of high mounts. You want to ride your bike or tinker with it for the next two years while you try to work out the tuning details? You want it to look like an I4 go buy one. In the long run it would be cheaper. You think your buddies on the CBR's run away from you now - wait until you have the performance problems associated with this mod. Just my .o2

I am running a 2-1 and love it. You gain in the low and mids while losing a bit on top. If your bike is set up with a Dynojet kit, it is virtually a straight bolt-on affair. I cut my header at the end of the 2-1 section (just before it re-splits to two pipes), cleaned it up with a dremel and fit the link pipe (am using a high mount Blue Flame can from a 98 Yamaha R1; it slid right on). I recommend the set-up, it pulls like gangbusters in the mid-range.

second, my buddies don't run away from me on my CBR since it is a wolf in sheeps clothing race bike. i run away from them.
third, find a good tuner and have it tuned right and you won't have any problems.
finally, thanks for your two cents.

If you look into the guys that have done the VFR singarm swaps, I believe most, if not all of them have a single exhaust. Any of them should be able to answer any questions you may have. Like epleeds above. Nice bike by the way.........

I love my 2-1 set-up. Before going the single can route, I did some research and found a few chaps on the UK Firestorm site who are quite knowledgeable about it. The consensus is that the 2-1 boosts lows and mids at the expense of a slight drop in top-end (verified on the dyno by some). Also, if your bike is stock it will need a re-jet but if you already have slip-ons and a DJ kit (properly calibrated), it is basically a bolt-on affair (as it was for me).

2-into-1 exhaust pipe pics
Hope this will help you get a better idea of how the exhaust pipe gets cut and welded. In picture 922, both headers are shown. The others show how the 2 pipes gets tied into 1 pipe as mentioned earlier by Gregw.

Yep, I cut my header in precisely the same place (at the end of the merge, just before they split again) I used a dremel to clean up the welds (to reduce turbulence and restriction, smooth out the airflfow) given that I had access to them. Hook up the link pipe there (2" diameter) and you're in business.

hmmmmm
You're the 2nd one here that I've read that's had a carbon can blow out.
I might have to rethink what I want.
