Custom exhaust maybe...

   I looked at Ron McCoy's pipe out in Co. it sounds a bit different than the Predator, it is the only one I have seen that exits on the left side of the bike. Which is not a bad thing just different.
    I also cannot see any problem with welding the " Y " pipe to items  # 3 & 4. The Predator has no joints in this area only clamps. You would probably need to tack weld the pipes while in position for correct alignment.
     I'm looking forward to seeing your set up this spring Tiger.
                                         Cheers Ken S.

So Ron, any pre-production thoughts on your patented exhaust system?

the predator Y pipe is not that great... you end up having to remove some of a crossover tube on the bottom of the frame, plus the xz550 is not listed on their site anymore

If you weld 3&4 to the Y pipe you may not be able to install the Y pipe.  I don't know this for sure, but in my experience it seems likely.  The way I did mine was to install the Y pipe without the #14 rings installed,
clamp the #15 collars to the flanges on # 3&4 with needle nose vice grips or small finger clamps, and tack them to the Y pipe.  Remove the Y pipe and weld out the # 15s.  Reassemble with the copper rings installed and your leaks will be gone and the Y pipe becomes a structural part of the exhaust system. This works with the stock exhaust as well as a custom exhaust. I've been running mine with this modification for over 20 yrs. It put an end to that rear cylinder exhaust leak that sounds like a really loose valve.

theres 2 kinds of loud exhaust on vehicles motorcycle four wheelers ect.. for example.. on my uncles 2003 kawasaki zx6r.. his aftermarket exhaust.. (dunno what it is) is loud and obnoxious.. and annoying..
then theres the nice low sounding loud rumble that makes your heart skip a beat just hearing it.. i like that!!!
kinda like tigers orange vision ;D

I don't think I saw anyone mention the name of the tunable baffles...Supertrapp is the name. They offer many universal options. Not cheap either. But they are stainless. The thing with this exhaust...the stock mufflers start out 2.5" o.d. I have been toying with cutting off the rotted mufflers on my spare and welding new pipe on. Then supetrapps on each side. I have a write up on it from years ago. But each supertrapp is ~ $150. So x2 is $300..ouch

NV. that is Supertrapp. I just would go with a universal unit. They make 3 types...3" disc, 4" disc short body~12" and 4" disc long body~16".   Supertrapps are truly tuneable.

Does anyone know for sure if the rear Y pipe will bolt to the front cylinder? I heard one yes already just making sure.

You could do it, but plan on welding the whole thing together..
I sold the  exhaust system from the Vision racer to Blake , 4 or 5 years ago , it used a rear Y pipe to siamese the two ports in to one pipe. the angle was a bit wrong but it worked . The thing was so loud  that  it made MACs sound posativly quiet . I seem to remember he was shattering windows near his apartment! ;D I have pics of the system .

....... the angle was a bit wrong but it worked.....


that's what I saw when I held a Y up next to the front cylinder. the angle of the Y makes it extend quite far forward, not terribly far from the fender, and points straight down.

there wouldn't be a whole lot of ground clearance after an immeditate 90, and there would be a consideral gap before it got back to the engine case. eyeballing it, seems like it would be half way between the fender and the engine case and pretty low to the ground

I'd be pleased to post the pictures of the Vision racer, but I have no idea how to do it . I can ,how ever attach them to an email . Is anyone interested in posting them if I email them to you?

Rider1>No wonder, the Daytona has very sharp steering and aggressive geometry.  It's a very difficult bike for a new rider.
Rider2>Well it has different geometry now.
