Will GS1100G exhaust interchange with GS1100GK?

[Markus Likeus]

I need a complete exhaust system for my 82 GK and in my search have noticed the 82 and 83 GS1100G models have an exhaust that looks identical to the GK. I have looked at the photos of the G models in the Suzuki Sales Brochure and photos of G models on the web and those with stock exhaust look like the GK version. I've done a search of the forums on threads and posts and could not come up with anything definitive using "GS1100GK exhaust"

The G and GK models use a Dunstall style muffler and not the megaphone style. There is a difference of about 6 1/2 inches in muffler length with the Dunstall being longest. Both models are shaft driven and both models use same gas tank and plastics. Both models use the same engine as far as I know. I removed both exhaust heat shields trying to find a number of some sorts but none exists.

I looked up the part numbers at Alpha Sports and the systems show different part numbers. So if they are different how are they different? I took some measurements from the stock system on my GK.

muffler diameter is 4 inches
length from rear of exhaust heat shield to rear of muffler = left 24 3/8, right 24 1/2

height measurements were taken on level concrete with bike resting on the center stand.

height from ground to bottom of muffler measured at rear of exhaust heat shield = left 10 7/16 right 10 7/16

height from ground to bottom of muffler measured directly under exhaust mounting bracket to frame bolt = left 11 3/8 right 11 3/8

height from ground to bottom of muffler measured at rear of muffler = left 14 1/4 right 14 flat.

Right now I'm thinking the only difference in the pipes between the two models is the amount of exhaust packing around the baffles. This maybe wrong thinking so I am asking for help please.

I have no personal experience with this but I've read here that the GK mufflers are slightly lower to clear saddle bags.

I found this on the internet so thought I would pass on. Marving mufflers, cost is $273.99 for two mufflers. Order from

I'm still searching for information on interchange between G and GK.

GS1100G and GS1100GK exhaust downpipes and mufflers are interchangeable.

I spent lots of time looking for a relacement exhaust when I bought my GK and I seem to recall the G mufflers did not work with the GK saddle bags... (but that was ~12 years ago and my memory isn't getting any better).....

It works, we just did it.

I had to do some fabrication just to get the bags mounted to the bike, but I had no problems with muffler clearance on "Junior", my 1980 850GK.

Click on Junior's link in my sig, you can get a hint of the fit.

Here is a picture that will directly compare an 1100GK on the left and Junior on the right.
