4 into 2 Headers for '83 GS750ES

Okay, everybody loves 4-1... I don't. I love 4-2.. I think it looks so cool! But try finding a replacement... So, I have a couple of questions:

1) Can I get my original 4-2 headers re-finished with a ceramic coating? Then, what mufflers will fit. I'm thinking of getting rid of the stock mufflers.

2) Replacement 4-2 headers. I can find 4-1.. But 4-2 seems to be a bit harder...
 
I doubt seriously you'll find a 4 into 2 for your bike. Even new there was only one or two available for these bikes. As for slip-ons, you could do it but with the seam that's in the stock exhaust where they would attach it will look cobbled together. You might find something meant for an early GSXR that will fit.

this is for the 83 750e/es stock was 2-1 on both sides is that what you want? 4-2 sounds like a back pressure night mare in my opinion.
 
4 into 2 exhaust turns into 2 into 1...

4 into 2 exhaust turns into 2 into 1...

You're completely right. I thought it was 4-2 for sure... I want 2-1 for sure.. I want exhaust on each side...

Any suggestions?

Do you currently have a stock exhaust for it in decent shape? As far as I know (perusing through the 1986 Dennis Kirk catalog), the only aftermarket exhausts for this model were four into ones (or four into two into ones) made by Yoshimura, Kerker, MAC, and Vance & Hines.
 
Yes, they are in 'decent' shape. I wouldn't even mind to keep using them, if I could re-finish them... I mean, I could I finish the headers in a ceramic coating? Could I paint/re-finish the exhaust so that they don't look re-finished? Can someone shoot me some examples of exhaust that will fit on the stock headers?

I've got Hayabusa cans mated up to the stock header pipes on my GS750EF, see if you like the look. You can click on link where it says "my baby" at the bottom of this message to see some pics from when I'd just gotten 'er on the road.

There's a guy here in the Bay Area who quoted me a black ceramic coating with a 60% gloss finish on my stock pipes, mufflers included. He wanted $265. A good price in my opinion. Far less than trying to find a new set.

Where are you located?
 
That DOES sound like a great deal! I live in South San Francisco. Like 45 minutes away from you dude.. Give me his contact info... THANKS!

It is 4-2. 2-1 is a two cylinder engine with one muffler.

As for suggestions, if your stock headers are OK, then I would use them and add a couple of aftermarket cans or OEM sportbike cans from fleabay. You should be able to find some 2007+ GSXR1000 cans for not too much money or some Busa cans, maybe even some Ducati cans.

I just looked at Macmatic's 750 and he used Busa cans. They look exactly like the late 90's-early 2000's GSXR cans. They mount with a 3 or 4 bolt flange (depending on the year) and are all over fleabay. I know you can get those cheap, they flow lots of air and are pretty quiet. The biggest advantage the Busa cans have is they came stock with a dual can set up, so there is a LH and RH can with the bracket set up for that side. They would be easier to mount that way...

One example from fleabay:

Yes you can!

Yes you can!

There are lots of options for the refinishing of your pipes. "Eastwood" sells lots of different heat and ceramic bake on coatings that you can do yourself. Also you could try the yellow pages for chrome and powder coat services, they also can refinish your factory pipes. I built and coated my own header for my GS850G from mild steel an mandrel bends from a local muffler shop. I used "eastwood" products to it. The finish turned out great and I spend less than a 100 bucks total. Good luck with your project...:)
 
You will need to keep your headers, you can get replacement megaphones BUT they will be chrome. I have looked high and low for black megaphones and can only come up with chrome ones.
There is a bake on ceramic coating that you can use to make them black, search this site for ceramic coating and you will get a few good links.
 
Yes, I'm going to keep the headers and have them ceramic coated. I'll see about getting the megaphones refinished. Not sure it's worth keeping the megaphones.. I like the kerker headers I see on many bikes and getting one on each side of the bike I think would look pretty cool. If if they are chrome..

The cans and pipes I used have a 3 bolt flange. To mount them the way I did you need to reverse the pipes L on R and R on L in order to tuck them in near the swing arm and at equal "rake" angles one both sides. At least it seemed like the only way when mated to the stock headers....

I'll have to look at see if I ever posted the How To I wrote up a couple of years ago...should still have it on a drive around here someplace.

Short version is this: To do what I did try to get an entire 'busa system. If buying on ebay see if you can get the seller to cut off the right side header outlet with as much pipe as possible so you have room to work with it. Toss the rest of the headers. Buy another header and repeat, two right side outlets would make the process simpler and allow more options when grafting onto the GS pipes.

Cut off your megaphones about where the pipes come out from under the bike. Tack on the 'busa outlets. Use the megaphone brackets to mount the busa cans to the passenger footpeg brackets. Line it all up just so and re-tack the outlets into position. Remove, weld, paint, install, vroom!
