GS1000S 4-into-1 exhaust system recommendations?

[Pantera Mike]

I’m lookimg to replace the stock exhaust on my 1980 GS1000S with something period-correct, but if I can’t find a 44-year-old system I will need to get something new. On EBay I’ve found offerings from Delkevic, Marving and Moto GP Werks. Does anybody have any real-world experiences or recommendations to share?

Thanks!

If you consider performance Hindle makes the best Gs1000 pipe. 4 > 2 >1 for better mid range

Relatively inexpensive, if it isn't tariff-ed

The 1979 GS1000L exhaust system is similar to the 1980 1000S system. The S system has different indents in the pipes for the brake and shifter, but most people wouldn't notice. There is a guy on ebay with a very nice set of these pipes, but he wants stupid money for them. Maybe see if he will make you a deal?

Search "GS1000 exhaust", then toggle USED

Look into Vance & Hines "Street Megaphone."

As I understand it, the Moto GP Werks is a replica of the Yoshimura system, so, most correct?

Thanks for the leads! V&H doesn’t list anything anymore, nor does Kerker, or Yoshimura. I can’t find the EBay auction referenced above?

When I briefly had two cooley's the second one came with a Hindle...was very impressed with it....found some 79 gs1000L exhaust and put them on it when I sold it...still have the Hindle

I just performed the search again, and they came right up.

For comparison to Trevor's photos, here is one of my old S's with the factory S pipes. A close eye is needed to notice any difference.

Oh, sorry, you’re referencing the E-bay auction for factory S pipes? I thought you were referring to an auction for a 4-into-1 system. Thanks!

Depends how deep your pockets are & if you want to run a centerstand..... The Delkovic the budget option but there is nothing wrong with it. Good pipe. Not sure if you can run centrestand but I think you can. I could on the 1100G that I ran it on. It's a similar shape & style to the Vance & Hines pipe (I ran one of those on a 1000G and also my 1000E).

MotoGpWerks - Local California guy. Does Amazing work. It's a Yoshi copy. No Centrestand & you'll have to remove it everytime you want to change the oil (I ran an original Yoshi on my 1000 for a while, it's a great pipe but I got fedup with the on/off part of it). I've never had one of his pipes but I've spoken to him, he knows his stuff and gets great reviews all over the interwebs.....

Marvin - Not stainless but the chrome is very good quality. I run this on the 1000 (after the Yosh, I also ran a V&H on it for a year too). The flat collector gives more ground clearance under the bike. You can run Centrestand & change oil etc fine.

Trevor -

I'm looking at your brake pedals on the 2 Cooleys. One seems to be more rearward, but the other seems to have a non stock engine (clutch) cover. Both brake pedals stock?

Hmmm good question. I never noticed. It’s just a yoshi decal I took off before selling.
I flipped that bike.

...a 4-1 just looks & sounds right.

You are so right.

Really? Oil sight windows look different sized.

I fitted the Delkevic pipe 3 years ago and it have been great. Good sound compared with the old standard system.

I run a supertrap on my 80 1100L, and Delkevic on my 80 850. Both are very nice pipes, the Supertrap is more or less period correct, tuneable and sounds great, as does the Delkevic.

I understand that there is a lot of interchangeability with Suzuki exhausts. Does anyone know if a GS1100E 4:1 would fit the GS1000S? I have an old Hindle, maybe 90's for the 1100E. They list different pipes for the 1000 vs 1100 so probably not. I'm getting confused if there are two threads on this subject, one says chrome V&H or ... Anyway I'm on the fence about whether to use or sell that Hindle. It weighhs 10 lbs and with stock exhaust and centerstand removed that's big weight savings. Plus you can pull apart with the springs to change oil.

Looking at the Ripplerock site Hindle does make a system that fits both bikes.
I would contact them directly.
