exhaust project
 
I scored a beat up pipe that was on a friends FZR parts bike, and I wanted a lighter/different exhaust on my XT, so I'm working with this scorpion pipe, which was very modified.

I have the pipe cleaned up and painted right now, but I still need to fab a midpipe up, which is the difficult part of this application. luckily, I have a friend who has a junk car I can pillage exhaust pipe off of, which will help make what I need.
I'll likely photograph more as I adapt exhaust pieces and make what I need.

on to the photos.

and where I want it without that cover so I can decide midpipe routing.

That Beast oughta snort with that little can on it!:thumbup1:
I've got the very same pencil'd in for my XT6....only I'm using an old Kerker alum. can from my old Seca550.

Takin' notes here :wink3:

this one, I think I have to purchase a pipe expander and borrow a bender for.

next thing up, is rejetting and fine tuning it all. I know she needs new jets after this little mod. besides, a slightly bigger pilot probably wouldnt hurt anyhow to aid starting.

my buddy will do the welding(assuming I need to join two pieces of pipe) and possibly bending, if need be.

Just put the side panel back on and run it, smile demurely if you get pulled.
Bending pipe is a black art, as is exhaust design, I'll be interested to know the effects of your efforts. I remember MVs with open megas, Ago n Read thrashin tarse of em made the hair ont' back a me ed stand on end. I was wondering how you could build a reverse cone mega in to that space n what difference it may make.

I'm playing with an idea in my head for a baffle setup, I'm just not positive on how to pull it off. it'd work in the stock can, but the aim is to remove that, since its a solid 10 pounds of excess weight I have zero use for.

the alternative plan, is to just leave stock pipes in, but the muffler weighs so much, and for me, restricts access. I hate stuff that blocks my path.

It would be great to have a gradually expanding, curved pipe from the header up to the small silencer box, but you'd need a tame snake charming sheet metal worker to make it.... and it may not work when done.....But would be simple,light and unobtrusive.

bobthebiker 11 Aug 2010 02:01

yeah, I'm not messing with that, not like my plan where I simply need to get two bends @35 degrees so I can mount my canister where I like. where I've got it worked out, it'll just need some pipe bent, and maybe some welding, but nothing too extremely complex, so I'm good.

oothef 11 Aug 2010 02:22

yes simple is usually best, trying to make pannier racks is teaching me that!

bobthebiker 11 Aug 2010 02:37

I've already decided I'm absolutely not doing THOSE on this bike. small saddlebags at most, and anything more, you can stow on the seat, screw it.

as soon as my friend gets back to me on the exhaust piping, I can really begin on this project. that happens to be my ultimate holdup is seeing what bends already exist in the pipe he has, and how much fabbing I have to do to make it work.

Hi Oothef,

I'd be interested in the design of your racks at some time. Any chance of a thread with pictures if possible?

Cheers.

Ive made a slip on Bandit can fit a DR 650 with a flexable joint. Tuner car shops make a flexable exhaust joint for performance modding car exhausts. I just called one of them up and told them to put two different sizes on it, 50mm on the 'Bandit' end, and 37mm or something on the DR end. Worked a charm. I'll try dig up a pic!

Never seen that, but thats clever, and so easy to use.

What did the little joint cost ya?

banditderek 16 Aug 2010 19:41

Not that much, maybe 40 quid?

banditderek 16 Aug 2010 19:42

And once you've got it sorted you have a much larger range of cans to choose from.
