Pipes look at those pipes!

Cosby was great but I am thinking of pipe design and welding.
I am wondering just how light pipes can get and still be serviceable in normal riding conditions.

I could lose 60 pounds but making a paper thin exhaust is so much easier after all. There is an added benefit in having a hot glow at night which will impress the tuner kiddies.

So whoe here bends pipes? Looking for this information on Google opens up a plethora of useless sales pitches.

How hard is it to get a custom pipe made for a bike? I mean if they can knock one out for a car at joe's muffler shop it cannot be that hard can it?

I don't know about weight but I have seen guys build them from premade Us and Js in stock sizes available from some autostores and on line sellers. A year or so back they did a set this way on an episode of "Two Guys Garage". It is fiddly and time consuming and probably takes a fair bit of trial and error but it can be done. I think it could be fairly difficult with 4 pipes and if I were to try I think I'd start on a twin.

It would be great if you had access to a mandrel bender but who of us do.

Go for it and lets see what you can do.

Cheers,

Seen a article that used plumbing like under ure sink to design some headers and stuff then made a jig and just used that jig to build a great exhaust.

Some parts to use ....... http://www.spdexhaust.com/

Titanium is as light as you're gonna get and have any sort of structural integrity and heat endurance to it. Ti isn't all that much lighter than Alu, in useable form but Alu has built in stress limits (it'll only bend so many times before it breaks, whereas steel has nearly infinite bends but will change shape)
Steel is much more cost effective, stainless is better quality but Ti is strong, durable, lightweight, and it turns pretty colours too but man it's expensive.

You also need a gas purged environment to weld Titanium cleanly. Ray.
