After market exhaust

Post by acruzer1000 »



Hi Everyone,

I have two stripped down 77 Goldwing GL1000's. One of them has a an after market Jardine exhaust and the other stock. I would like to replace the bike with the stock exhaust with a Jardine but unfortunately Jardine doesn't manufacture the slash cut pipes anymore. I've been having back issues lately and noticed a considerable difference in bike weight when moving the bikes in and out of my garage. The bike with the stock pipes is slightly heaver than the after market one. That stock pipe must about 25 pounds or so I guess. Anyway, if anyone out there has an old pair of Jardine full exhaust slash cut pipes that they want to part with, please let me know. Much appreciated, thanks! Happy and safe riding!

I have a complete Delkevic exhaust system that I removed from my '77 Wing, from the heads back. They sell for $600 on eBay ! It's all stainless steel, a little throaty but you can have it, just pay the shipping.

There are quite a few people 'out there' that would be interested in your stock muffler if it is in decent shape...

I know this post is a couple months old now but I have some questions about the muffler options for a GL1000. I am working on a '75 GL1000 right now. The stock muffler is still on there and seems to be intact. The bike also came with a set of HM431 mufflers. They look to be in decent shape too. Will these fit the GL1000? Trying to decide whether to keep the stock or put the HM431s on there.

I haven't been able to find much info on the HM431 exhaust.

I also have a second GL1000 from 1976 which I have plans to modify and I would be willing to sell the muffler. I haven't found too many of these out there to get an idea of what to ask for it. Thanks!

I know this is late and you are probably well part this now but.......
431 is the model number for 78/79 GL1000. Those mufflers will also need the same year headers and you will have to fabricate rear hangers.
Also there will be sidestand interference unless you change the removable lower left frame to the same years.
'Impossible' is just a level of difficulty! The only stupid question is the one you didn't ask first!

( Seriously, you haven't read all 115 pages of my http://www.wingovations.com website ?? :shock: )

if your exhaust is still available I would be interested in purchasing

Dfred. Yes I still have it. Send me a PM.

Btw if anyone is interested. The hm431 exhaust and headers fit on my 75 gl1000 perfect. No issues. No modifications needed.
