What GS did these exhaust systems come from?

[Nessism]

Anyone know what model GS these exhausts are from? The parts are imprinted GS110X so I assume that means GS1100. Since these systems are black I think that means 1983. The parts fishe for the 1983 GS1100E shows a heat shield but their is neither the shield nor a boss to bolt one too. Is the fishe wrong by chance? The Katana model pipes don't have a heat shield, but not sure if these could be Katana pipes.

Any advice appreicated.

The black chrome was Katana pipes if i remember right...

83 1100ED/ES had black chrome pipes as well.

Also some of the 700/750s did as well I believe as did the 1150. I cannot recall how the beauty shield attached though...

If they're the same as the 1150 pipes, the heat shield clamps on. There is no stud on the pipes themselves.

There is a set of supposedly GS1100ED pipes on ebay but they look slightly different...http://www.ebay.com/itm/29057434222...spagename=STRK:MEWAX:IT&vxp=mtr#ht_2913wt_889

The seem to have bolt on exhaust hanger brackets (these ones are welded), plus they have the heat shields.

'83 1100E's.
Here are the numbers off of two of my sets...

Check your numbers.

Hummm... could it be you have a wee bit of gold mine there?

Looks like the same numbers on the pipes, no heat shields and welded on muffler brackets.

Joe Nardy is on line. Ping him with DGM36893S and see if it matches the ones on his Kat.

Sorry Ed, I didn't see Eric's post until after I posted.

700's were all chrome

The '83 GS1100E has a 4 bolt on heat shield.

Yeah I wasn't sure which was which, just that that era some had black pipes.

Ed,

I can check numbers later today. I have two sets of '83 pipes which both have two mount points for heat shields on each side. The Kat pipes which, as pointed out, do not have heat shields. As far as I know my Kat pipes are original and complete.

Thanks,
Joe

Thanks Joe,

I'm curious to learn if your pipes have any kind of boss for bolting on a heat shield. The parts fishe suggests a boss for the rear heat shield attachment point. Also curious to learn how the numbers on the pipes compare to those of Eric's and my pipes.

Take care

Ed

Ed,

Here are a few pics that may help. Sorry for the quality, the pipes are stored on a shelf above my garage door and I had to shine a flashlight on them to get decent pics.

Katana left exhaust:

'83 GS1100E original exhaust:

'83 GS1100E 'new' exhaust:

'83 GS1100E original rear heat shield boss:

'83 GS1100E 'new' heat shield and bosses:

It looks like all the mufflers have the same number stamped on them. My guess would be that they use the same muffler and attach or do not attach bosses for heat shields depending on the application. Let me know if there's anything else I can verify to help.

Thanks,
Joe

So Eric,

Do your exhausts have heat shield bosses welded to the pipes? Maybe that's the only difference between the regular 1100E pipes and the Katana?

Thanks for the help Joe. Since these exhaust systems I have do NOT have any heat shield bosses, do you think they are most likely from a Katana?

Ed,

That would be my guess unless they are from an 1150...scratch that, it looks like the 1150s have heat shields too. The only other black pipes I know of are the later GS550s and those look to be shorter. You might want to check with GS Scott. He is very well versed in the differences between the E, ES, and Kat pipes.

Thanks,
Joe

Exhaust pipes

Ed,

The 110(X) says they're 1100 pipes.
The difference between E and Kat pipes is just the location of the hangar, and the heat shield.
Kat pipe hangars are closer to the middle of the megaphone, where E pipes have the hangar closer to the front end.
82 Kat pipes (for the 1000) have the same part number (as confirmed by Joe), but they have silver painted exhaust collars.
83 Kat pipes (for the 1100) have black painted collars.
Also, 83 pipes have a slightly larger center exhaust exit opening compared to the 82 model. I'm fairly certain this is due to the cam changes in 83 which had more lift in both intake and exhaust. I've had to run 83 E pipes on my 82 Kat while I tracked down a set of Kat pipes, and they needed jetting help.

So it looks to me like you have two (2) sets of 83 Kat pipes.
These will of course, fit perfectly on an 82 Kat as well as 83.
Major score.

Polish them up and they will fetch a good penny.

Wow! I guess you just gotta know who to ask, huh?

Nice work Scott!

Also explains why I said that my stock GS1000G (Goldie) felt like it had more power with the 1100E exhaust rather than the stock 1000G pipes.
They flow better.
