what gauge piping should I use for the header on the gs exhuast. I beleive 1/4" would work? ideas?
Im going back on active orders at my base for 3 weeks and Ive got access to the manderal bender but I want to figure out everything before I order all the materials.
I want to create somthing much like the new gsxr's have and my vance and hines is all nice and scratched up.
try like 1/32......
1/4 would weigh 80 #
and if you have access to kewl stuff......TI is the bling way to go
yes yes Titanium is very cool very flexable too. one of the metals I had to certify in welding with the airforce. but for weight reduction that would be a prime choice. I am going to check with our local metals supplier for prices on Ti. its pricey i know but I may beable to get a govt. discount.

I'm sure you mean "military discount". Gov discount means you're ordering it for Gov use. Miltary discount means you the individual get a discount for being in the armed services.
I'm still trying to imagine 0.25" wall exhaust tubing... :o

that would be Schedule 80 pipe.
Lol!!! That would be like a lead brick hanging of the motor. Wonder if the exhaust studs would hold it?

Nice! You could just go to the hardware store and get some black pipe sections and a couple elbows and you'd have a new exhaust in no time! If you wanted more corrosion resistance you could go with galvanized instead of black pipe :thumb:
mmm... 50 pound exhaust

no I ment govt discount. you call up the local metal supplier who deals with you tell them you are ordering it for the shop and pay out of your own pocket. not many people give a military discount anymore. only a few places do and some people are nice enough to make exceptions and give you a discount anyways even if they dont have a military discount.
I really had no idea what size wall I should use on the pipe because I am not an exhuast expert nor claim to be lol. so how thick is the wall on the exhuast pipe of our bikes?
sorry for the questions that seem to be obvious if I would just go measure them myself but I do not have the bike at my house I have it at my storage space ready to be torn down.
thanks for the help so far
I'm making an exhaust manifold out of sched 80 black pipe....need something to support the extra weight of the turbo and handle the heat :icon_mrgreen:
16 to 18ga is common for exhausts. I would not go any thinner than 20ga.
ok i stopped by my space today and pulled the bike apart got the vance and hines system off and im going to use that for all my measurements. I am going to cut the exhaust short. tuesday I should start the design
+1 geez! If I sold that stuff I'd give him a discount. Its not like he's stealing any thing. Its a frikn discount.
Take pics! I wanna see how it comes out! What are gunna use for a can?
If you can't give military personnel who put there butt on the line to keep yours safe, who do you give a discount to? He's military, not a lotto winner & like the rest of us, isn't rolling in cash.
Ya know dude, your a butthead! I give people military discounts all the time, I'm a frign plumber. Young and in the service, or old and served in ww2 or some thing. Hell I've done stuff for free for some retired people. I guess they stole, they have no morals or integrity? Dude, someone how respects gi's is given this kid a break, so frign what? He's maken a toy?
Back off the kid and worry about a real problem!
anyways. not worth me even answering.
but thanks for those who defended me . in all sincerety I thank you.
this will probly make Wierdo happy. our local supplier does not stock Ti, I might be looking at other avenues such as ordering on ebay. either way I will get the material. I have an idea of how I want to run the pipes. do you all think it will hurt my performance to run two seperate pipes and have then stop right b4 the rear wheel and angle back and out? I will try to draw what im thinking.
and if my integrity doesnt satisfy you then I hope it will satisfy the rest of the US when I go to the middle east because Im not going by force I volunteerd .
I hope to start on the project this week. I stopped by my storage space last night and took the bike apart and got the vance & hines to use as a template kinda. it actually is pretty thin pipe I was surprised. I dont know what I was thinking when I said 1/4 :cookoo: I guess my head is stuck on making hand railes at work!!! because my civilian job is a shop forman for a welding fabrication company but I honestly hate it and try to pick up as many active orders as I can. hintz me going back on active orders for the next month and hopefully for a lot longer this time.
and jerrett just out of curiosity what branch did you serve and what did you do. because obviously you don't understand the buddy buddy brotherhood of the military.
Susuki_Jah:
Thank you for serving, and kudos to you for not rising to the bait of posts with personal attacks that I've split out from your thread and moved to the TF.
Jarrett:
I'm moving your personal attacks into the TF. Enough of the personal attacks. Obviously, there aren't too many in your book who have personal integrity, who aren't liars, and who aren't perpetrators of some evil fraud. It gets old. It may be that black and white to you and your branch of the service, but this is GSTwin, not the armed forces. Keep the personal attacks out of the General Discussion section (and off of GSTwin).
It would seem to me that there would be codes of honour having to do with respect of oneself and others, and it seems to me that personal attacks would fall somewhere outside the honour part.
I'm all for honesty and integrity, and I'm all for upholding the codes of honour in the services, and I also recognize that members of the services are encouraged to help their brothers and sisters in arms walk the straight and narrow. If anyone feels the need to help one of their brothers or sisters in arms, do it in private message, do it respectfully, and don't make public (or private) personal attacks.
**Sarcasm removed.**
ok first day back in the shop. ive finished almost 100% of my work load for the next 3 weeks today! worked my tail off. so a little more time to relax and design. :) im going to try to draw my idea tonight and get some feed back from yall. Ive found the distributer im going through to get the Ti. going to order it this week. Ill tell you the damage when I get the bill lol. Pretty soon I might be merging my civilian job with my active duty and work for the base full time.
btw: not that It should matter but I am 25 not quite a kid anymore lol ;)
Hey, I didn't mean to offend when I said kid.... Man man man man! Better?
How about a maybe a high mount pipe with a bolt type flang that will accept the wileyco can? That would be hot and you can get those cans cheap when available. I think they are on ebay now...maybe.
.02 worth.
Kid!
:)

hah no offence taken. somtimes people view you differently when they actually know your real age . for better or for worse.
I dont know if I really wanted any cans. I was thinking of straight piping them. but I do not want to kill my performance. I have the vance & hines system now and the bike feels very strong and will take a stock gs500 to the cleaners lol. I have other mods though. but anyways. I was trying to get away from having the pipe run up on the back I like the clean look but I also wanted to make it cemetrical and run two pipes.
here is the drawings of the idea's I had I would love some performance related input. I just dont want it to hurt me. I could care less about the gain , although the exhuast will be lighter.

I can tell you right now that the system drawn won't produce enough backpressure with no cans.
It looks badass though. If you look in "the thread about the nicest GS ever that won't die", you can see something Jim Knopf did that's similar, but they exit a little farther back.

ok so not enough backpressure can result in burning up your valves correct or is it rings... the vance and hines system how much backpressure does that actually produce I mean its so loud that I figured it barly has any back pressure as is. but what style can do you think I can use that will be small and light weight could fit under the bike without creating problems. somthing very short or just enough to give me the pressure I need. I was thinking Idea #2 would give me some back pressure. but Ive got to do some serious perfect bends and cuts to get the perfect tig welds, fill the inside with inert gas to get good smooth beads on both sides.
What about putting a baffle in each pipe for back pressure ?
And then selling your Vance and Hines to me for cheap for my race bike :icon_lol:
Anways, if you are welding up Ti, do something like Rossi's bike

The thought I had awhile back was chopping up a buell can for use as an underbelly exhaust. Just a thought though, not sure about the logistics of it. Send a PM to makenzie71, as much as people like to bash him, he knows a bit about plumbing. Also PM GeeP, as he knows a good bit about the subject (damn MEs)
Have you ever listen to a gs with straight pipes? I fired mine up when I cut the can off and it was WAY loud, but sounded like hell!
Loud is fine, but its gotta sound good too

definatly cool I wonder where I can find that tiny little can on there. I havent done much searching yet though. I would still make the exhuast shorter and lower in line.
well my bike does sound sweet with the V&H but its so loud that it will hurt your ear drums if you dont have ear protection or a helmate one so it led me to beleive that there is really no restriction on that pipe. lol i have no idea how long the system has been on the bike btw.
but the idea with the small cans and two induvidual pipes sounds kinda cool or do you think i would benefit better with two into one with one can?
I know the Vance & Hines is loud, but you have no idea how loud that bike will be with the set up you are considering.

cant be any louder than a 302 running open manifolds ;) lol. I had the experience of hearing a kz750 with each exhuast outlet seperately piped straight and then ran under the bike seperately. sounded like nascar lol. well I figure when I do this if I dont like it I will only be out the money I spent on the Ti. but .. I want to find those little mufflers and place at the ends. but I do not want it to be any more qiute than the V&H actually I like Loud!
cool ideas!
I do remember seeing a pic of a GS with an underbelly buell can a while back somewhere.
I think the ride height had to be seriously raised to keep the can from bottoming out.

I figure if I follow the same diameter pipe all the way out and under the bike I will have no problems with clearence. we will find out next week when I start the project.

How about those? I used them on my Monte Carlo SCCA car and they got it down to track legal pretty easily.

I saw a bobber that looked like it had straight pipes... But when he started it, it wasn't very loud... So I had to ask...
He took the tweets from a bug exhaust (for those that don't know, the tweets are the little chrome (or rust) pipes that come out of the back of the bug... Called that 'cause they make a tweet noise) and welded them into the exhaust... Filled in the difference to make them look totally straight, ground it smooth, and chromed 'em...
There was just enough pipe passed the baffles that you couldn't really tell it had any baffles at all...
Sweet idea! :icon_mrgreen:
