Frustrated finding Exhaust

Postby bluec10 » Wed Jul 27, 2011 4:24 pm



I'm frustrated with the process of finding mufflers for my 1979 Goldwing. I don't need an entire system - just the mufflers. MAC Performance has some, but they are only listed for '76-78 GL 1000s. How are the '79s different?

I don't want something very loud - just a good set of exhaust pipes. Does anyone recommend a universal fit option if the MAC performance pipes really don't fit?

Thanks for your help - exhaust is the last thing I need to really get this thing on the road.

I put on a pair of Harley "cast off" mufflers on my 76.They were free to me(next door neighbor).Very little modification and they sounded fine.A little more throaty than the stock.
A Harley dealer may have a box full of them cheep.Ask or look on your local Craig"s list or at the local gathering of hogs.I wouldn't spend more than $10-$20 bucks each on them.

Or you can do like I did and run 36 inch straight pipes.

I wonder what effect changing for stock mufflers has on the carb jetting?

I cannot tell you, I modified mine to run a water-cooled Weber progressive two barrel.
That one however, I can tell you doesn't seem to care if you run mufflers or straight pipes.

The harley pipes I used pretty well matched the engine specs.After a electronic ignition,electric fuel pump,syncing the carbs,It would near rip your arms out of their sockets.First wide open throttle in first gear to 8 grand scared the be-jeepers out of me :shock:

Did you know in 1975 the GL1000 was the second fastest bike in the USA. The K1 was first ,.

No jetting changes needed with a GL1000 for many muffler mods, the Harley take offs included. They have very similar back pressure to the GL1000 muffler and the bikes are not much different in exhaust flow (similar exhaust flow rates). I used Harley Sportster muffers and they are quite and very nice looking IMO.

Harley dealers often end up scrapping brand new mufflers that were replaced with loud mufflers. Some dealers will give them away for free. Seems a shame to scrap brand new factory tune exhaust. Some of these owners are going to wish they had them back as many areas are cracking down on loud mufflers because people are getting so sick of hearing so many of them so often.

I NEED A COUPLE OF MUFFLERS TOO...SO IT'S NICE TO KNOW HARLEY D CAST OFFS will work fine for a '79 GL 1000 since I'm considering purchasing my neighbor's 5 years parked GW for $150 AND GETTING IT RUNNING
HE PARKED IT BECAUSE IT NEEDED THE THROTTLE RETURN CABLE EITHER THE TOP OR BOTTOM RETURN?

Went w. Mac turn down. Fits well. Headers blue after 1 ride. Thinking about wrapping the headers.

Blueing is nice IMO. Wrapping is certain to trash nice headers that are not ceramic coated both inside and out. The wrap does make the metal hotter, and traps moisture after rain, etc. So I have been told it is best to ceramic coat inside and out before wrapping if you want more than a season and a half out of your pipes. Wrapping was my plan, so I had them ceramic coated. The problem is that once my nasty looking stock headers were ceramic coated, they looked a bit to nice to wrap. My avatar has the bike after the headers were ceramic coated.
