Well, my H pipe was falling apart, and I was having to JB Weld the right side pipe every couple months or so. I finally decided to dump the H pipe, and runs some pipe back to the Harley mufflers I have bought a while back. Its not pretty, and there are some minor exhaust leaks where the flex pipe joins, But it gives me an idea of the sound of the mufflers and a dual exhaust setup. I will likely take the bike to a local muffler shop and have some custom pipes made to run back the the mufflers.

I also had considered doing a 2 into 1 setup running the pipe under the engine and coming out only on the right side of the bike. Do you think all the volume could be handled by ONE of those Harley mufflers??

If I run the pipe under the engine it frees me to lower the foot pegs a little.. I am a bit cramped on the bike.



Let me know what you think of the sound.. It does sound better in person... deeper. I was suprised how much louder it is than the old mostly empty stock mufflers.

It doesn't sound all that bad to me but at 72 I am half deaf anyway.

I think it looks & sounds great. How does it perform? The engine is tuned to perform with stock exhaust. Let me know.

It runs good, I have not noticed any real improvement, or reduction. And I have not ridden it enough to see if the fuel mileage changes. I was told that these mufflers give about the same back pressure as the stock ones. Just the tone and volume are a little different. I think it will sound better once I get all the exhaust leaks fixed. You can hear it in person, I need to get some high temp silicone and fill in the gaps where the U clamps are. Gotta get that at a "Speed shop" local auto parts stores only have silicone that's rated at 700deg F. I will post again when I get it totally sealed up.



Thanks

Has anyone tried the Motad 2-1 system from the UK? It's supposed to work without any fueling changes. But I'd be surprised.



Although it worked fine on my CBX750.



I'm sure the shorties on my bike are a lot louder, but I still have the H-box.

I ran a Motad 2-into 1.Superbly made Exhausts.Designed correctly to not need re-jetting.Very quiet,low note exhaust.



Bandit will have one running soon with luck on one of his GL500 Silverwings.

I got my bike back a couple weeks ago after getting the piping done. Dumped the H-pipe as well and also have the same mufflers. I also wrapped them:

I love the sound, but its running too lean now and the right cylinder is popping on deceleration. I gotta figure that out this weekend.

What does the "H" pipe do exactly? Is it better to leave it or do what you guys did and just do a dual exhaust set-up without it? I assume you would have to enrichen the mixture or go with a larger jet size?

Sounds a lot like mine, and it's been so long since I had the original mufflers on I forget what they sounded like so I can't compare them to the Harley can's but I seem to remember the sound being not louder but deeper. I noticed your seat looks a little beat, if you want to try to recover it yourself you can get pretty good, cheap cover material from JoAnnes Fabrics or a similar store.



Are your harleys baffled still? The one's I bought didn't say they'd been modified but when I got them I could see through them end to end. I've since installed a set of 6 inch baffles and it's lowered the noise a bit.

Do you have any pictures of the setup? I checked oldbikebarn, and the pic they had was terrible. Its a lot of cash for me.. I am thinking the muffler shop can do a custom job to cover my needs.. If I am gonna redo this completely I really want the pipes away from under the pegs. I have plans to lower the pegs and you cant do that with the pipes in the way.



Thanks for all the comments and info guys.. super helpful. I could not reply to everyone., I am a trucker and not home that much during the week.

Hi Ken.



Sounds good.



I'd also like to lower my pegs, so was considering a 2 into 1. Keep us posted on your exhaust system and peg mods.
