Custom exhaust maybe...

[Tiger]

 :) I'm thinking that, just maybe, over the winter period...trying to fashion a 2 into 1 system for one of my Vision's... :-\

I could use: The MAC front pipe, the rear "Y", have another piece fashioned from the "Y" to the end the front pipe, use another "Y" to bleed into a slip on...R6 stock, Kerker, etc... 8)

What say you, those smarter than I... :-\

Any reason(s) why it would/wouldn't work... :-\

Your thoughts and idea's please... ;)

I've been playing mental gymnastics with about the same idea.  Haven't found a why not yet.  Something about great minds . . .

I think as long as you end the system with...forget the name...the plates you add or subtract to change backpressure.  you'd be fine, it'd be more $$, but if your going to do it right...

Baffels?

That's "baffles", Dave. :)

(unless it's made from glueing together bagels, so a baffle made from bagels would be a baffel).

(what have I been drinking)

Tiger, I've been thinking about that stuff for quite a while too. I guess what's stopping me is that, to do a good, proper job, a pipe bender (the type that's not too expensive when on sale at Princess Auto) would be key I believe. I do have the MIG welder, so now I'm just one tool away from being ready to try.

I think that starting from good quality, right gauge pipe is also better than playing around with too-thin off the shelf repair parts from the auto parts store (like what you find in the bins at Canadian Tire on this side of the border).

Contact Ron McCoy.  Have seen his custom system and it's on the same level as the Preditor system in every way except price.

I've been thinking about a custom exhaust as well.  Planning on putting it together with donuts and u-bends as needed, not as smooth as bent tubing, but hopefully a little easier to put together.

My biggest question mark is what to do about mounting it up to the head (well that and choosing runner lengths), my fallback is to just chop up the stock system for as much as possible.

Sounds like a Supertrapp silencer.  That's what I was considering using & even though it would drive up the cost, doing it as a dual system, kind of like the MACs but with a silencer on each side, eliminating the necessity of removing the lower MAC can when servicing the rear wheel / tire.

A visionary in Mn , DT, built such an exhaust system  it worked and looked great!  he used the front pipe from the MAC exhaust . When he sold the bike the new owner didn't want the MACs so he gave then to me  , I'm still running them. I've thought about a custom system , but I've got so many things going I never get to it.

[XZv2]

Tiger, I have a left-side-only silencer system on my present XZ with sidecar (converted standard parts, eh Dutch imitation of standard parts) and I am making an only-left-side system for my future XZ with sidecar.
I do not understand why all aftermarket single-silencer-systems are at the right side. It is so much easier to remove your rear wheel if your silencer is at the left side. Your axle goes out right and you have more room to wriggle out the wheel if there 's no silencer.....
I did not find any disadvantage of the left side set-up. I would like such a system for my non-sidecar XZ also.

If you make a complete system from scratch, I advise a left side silencer or complete left side system. My two eurocents.....

my standard system looks in good nick an the p/o has had the down pipes made from stainless steel.I was thinking about making a single rear pipe system using the stainless pipes but so the original system could be refitted for the mot test as they are getting a bit keen on none standard pipes over here.I used to make most of my replacement systems up with exhaust sections from my local car breakers.Its amazing how many people fit new exhausts then scrap the car.

[Tiger]

 :) I think the after market system's go up the right side to give the "V" a symetrical balance...given that the drive unit is on the left side. However, I think XZv2 idea is a sensible one. Mounting an exhaust on the left side makes it easier to: Remove the rear wheel, adjust the rear brake, check the brake stabiliser bar fastener's, etc... 8)

arfa vmax your a man after my own heart ;) I used to love the old wrecker's yard's back in the U.K. I got many a good bargain from them, especially exhaust system's...car and bike ;D :D :D :D

Like your thinking 'Pou...Princess auto for a pipe bender...Hmmmmm, "Hey Honey I think you can buy me a pipe bender for Christmas" ;D ;D :D :D :D :D :D.... 8)

Thanks for the input everyone...keep it coming 8) I think we may see several custom exhaust's next spring, eh!!!

                       8).......TIGER....... 8)
p.s. Does anyone have picture's of their custom system that they can post ??? ??? ???

[Brian_Matthewson]

I've also been thinking about a custom 2 into 1 exhaust, starting with the Mac front pipe.
Take a look at Superfly's V in the gallery, about 5 rows down, it uses a Supertrapp and he says he loves it. He found the "Y" pipe in a scrapyard.

[jasonm.]

One thing not to forget is the weight on the rear "Y pipe". That Y pipe only has 2 copper rings and compression clamps. It is not the strongest design. In the stock design, most of the weight is supported by the passanger peg brackets and the stiff front pipes meeting in the middle. As long as it is no heavier than a MAC rear pipe you will be fine.

[Extent]

I thought a bit about the right v. left thing myself, I think there was a little more room for the plumbing if it was on the right, but I'm going to try for a highmout right side exhaust myself for mostly vanity reasons.  It doesn't hide any of the "cool" side of the swingarm and it helps to hide some of the spindly right side.  It shows off the exhaust better when parked, since it leans left, and heat can dissipate up and away from the bike, rather than into the tail plastics.  It'll help counterbalance the shaft weight.  And most importantly I always seem to fall on my left side :D

I want to try and get rid of the stock Y pipe configuration and replace it all with slipjointed springs.

[louthepou]

Ok, anyone would see a problem with welding the Y pipe to the parts that receive it exiting the cylinder head? These two thingies are bolted on the head, and they look like normal steel... unless I'm missing something, that sounds like a potential plan?

I think I'm talking about parts 3 and 4 on this picture.

[Tiger]

 :) 'Pou, that would give you a, sort of, front head exhaust set up...one more less leakable joint area ::) That would also eliminate Jasonm's concern... ;)
Depending on the "other end" set-up, would you be able to get the newly welded "Y" pipe up and in, from underneath the "V"... or ???

                    8).......TIGER....... 8)

[louthepou]

Nope, indeed. That would have to be done with the engine out of the frame, with the new "upgraded" Y (should I start refferning to is as "Super Y"?) then bolted on, and then slide the engine back in the frame.

But once it's done, no more bleeding finger joints trying to slip the clamps and the copper washers on...

you should be able to put the Super Y in without dropping engine... basically, your Super Y is the same setup as the predator:
