I don't like pipes like my brother has on his Harley they are annoying and the old saying "Loud pipes save lives" just doesn't cut it with me. However while restoring my 1984 GL1200A trike I wanted a low rumble not a loud annoying rap. I used the stock headers and attached a single stainless pipe @ the stock 1 5/8" into a MagnaFlow Performance Muffler Center Inlet / Center Outlet - 4" Round Muffler Part #: 14444 (polished stainless) on each side with the outlet into 2" stainless ending in a stainless FlowMaster Round Rolled Angle-Cut Exhaust Tip Part #: 15360 with a very lightweight baffle inside the 2" pipe. This was paired with a K&N filter in the air box and topped off with a new set of jets designed specifically for the bikes configuration from www.carbjetkits.com, they have a wonderful calculator on their website that takes into account everything mentioned above including the altitude and temperatures you normally ride at. The result is a wonderful mellow rumble indicative of power without any annoying blat and no deleterious effects. Just make sure you can find someone who really knows how to synchronize your carbs that was harder than anything else.

I put the Cobra 6-2-6 mufflers on mine. Gave a nice sound, not loud like a Hardly or tinny like a VW. Just a nice rumble and has been complimented many times by other Wingers. Just a thought.

Thanks for the input. Unfortunately most manufacturers including cobra don't manufacture for the older bikes anymore. I have found I wind up going to the UK for a lot of aftermarket accessories for the GL1200 they are very popular over there. Just got a custom polished stainless radiator grill from Wicked Wolf, very nice quality.

Great thread for the most part. I don't think I want to argue combustion dynamics with canucks623 or eklimek. :D

Interesting thread for sure! I put a set of Cobra's on my 95 SE & probably ran them 70.000 miles with no damage to the bikes engine. Nothing done to the carburators either. Nor was there any noticeable increase or decrease in power.
Took them off the bike & put back on the stock mufflers when I sold the bike. Then sold the Cobra's for what I bought them for. LOVED the sound of them.

So much so I may of found a set of used Cobras for my 1800. Seriously thinking about it.

I have ran open pipes on ALL of my bikes dating back to 1971.
This includes several CB750's, Gl1100, Gl1200, and my GL1500...
Even while drag racing in the 70's on the 750...
NEVER had an engine problem...
I guess it pays not to listen to the experts...
Ahhh your probably one of those really annoying people to ride with too then. Disturbing everyone around you whether they are on a bike or on the sidewalk. There are towns down here that have 85db laws and if you are heard over that you get a ticket that will make you think twice about those open pipes.
I think that is a great idea. I often wonder how all the Harley riders get away with running straight pipes and producing so much noise. When I was much younger, the police were not very tolerant of loud cars (glass pack mufflers could get you a ticket) and you didn't dare run straight pipes on bikes, now most Leo's don't seem to care about the noise? :shock:

For what it's worth:
When I bought my 2008 wing it came with a set of "Torq Loopz" installed in place of the catalytic converters (could be a problem in some states that require smog testing). The bike is a bit louder (maybe 3-4 db), most noticeably at low speeds and idle. The bike doesn't seem much louder to me on the highway and there is no droning. The Loopz are advertised to add torque & HP and while I can't verify that, the bike does seem a bit stronger than others I have ridden with and on. I'm not positive the mufflers are stock (bought it from a dealer so I never got to talk to the previous owner) but I think they probably are. It does have turndown tips on the mufflers but I don't think that would affect the sound.

I like the little bit of additional noise which is not at all obnoxious but much better than the "sewing machine" hum of stock Goldwings. ;)

I did find a used set of used Tri Oval Cobras & have them installed in my 1800. I like the sound, In all honesty I've only rode it a few miles, Central Wisconsin weather needs to warm up in order to test them further. So far I'm liking the sound & hope its a happy medium. Giving the bike a happy growl while not fighting to hear the radio. Time will tell

Glad I visited this thread. Just went on very long ride with mostly Harleys and they (and a GL1500 guy) said I needed to make the exhaust "grumble" so the guys behind would know I was accelerating. (we were in the mountains and trying to stay in tight formation) So I first checked availability of mufflers but thought I should go here first and man am I glad I did! My 1800 runs perfect and I'm not about to go messing with tuners etc to try and compensate for the lack of performance. It's a wing, not a Harley. They'll have to learn to deal with that!

Tell the Harley riders to muffle their bikes and they could hear how a real bike runs, or just blow by them and save your ears.

The Harley guys should be able to figure out that you're accelerating based on the fact that you're getting smaller in the distance. :)

When touring I prefer listening to my stereo system and not the exhaust. I can't think of any reason to make my exhaust louder. If I was trying to eek some performance out of the motor and the exhaust ended up being louder that is one thing. Make the exhaust louder just because you can is just a way to be annoying to everyone around you. Honda motors from the factory are extremely reliable why would you want to change it.
I agree completely!!
The best thing about a Goldwing is peaceful silence!
If ya want a lot of noise, buy a Hawley! :lol: :lol: :lol:

Another thing about changing the exhaust is don't do it without changing the intake. Harley's have Stages in which they increase exhaust output and it also changes the input. To get more noise and open the exhaust, you also have to suck in more air. So that means a free flow air filter to go along with open exhaust. And, don't forget the Racing engines are torn down and rebuilt after every race. Because of several factors and one being fixing the valve seats.

Can't think why you'd want louder pipes on a wing, it'd be like squeezing the nuts on a race horse to make it scream while it's running
