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 can’t find the EBay auction referenced above?

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.

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.
