question about pipes :)

Postby made2care » Mon Dec 01, 2014 10:54 am



So, I'm wanting to remove the stock muffler and just add some short pipes. I am wanting a louder bike.
Question 1- Will i have to modify the carbs at all?
Question 2- Can i just go down to my local automotive store for the short pipes?

thanks for your help.

You can put a set of short straight pipes on, it won't make an appreciable difference to carb jetting and/or exhaust valve temperatures. Unlike some bikes, it seems the Goldwing is not as sensitive to exhaust backpressure.

So now you want to turn your Sleeping Beauty into an undressed **** in a pair of hot pants, and now with a loud mouth?? :D Where will it end :?:

I can always count on REDIAL's humour to make my day. Yes, she will be loud !! :D
Another question . What size pipe would I need to fit on my header pipes. I guess I could remove the muffler and measure, but would like to order some slip on's or a shorty pipe soon. Would I connect the header pipe to the interior diameter of the shorty pipe or visa versa? this is on a naked 87 gl1200 interstate.
Thanks again for your help.

All parts from the engine should be slipped into the part away from the engine like so: header>mid pipe> muffler> tail pipe. The header slips INTO the mid pipe and so on.

I was wondering the same thing. I talked to an old school car mechanic that I work with. He started in with the back pressure issues and not knowing about smoking due to the oil coming up in the cylinders not to mention possibly having the carbs run rich yadda yadda yadda. If it's that big of a concern then can't one cut off the ends of the pipes they don't want and measure the smallest inner diameter it goes to and simply find a grade 8 washer with the same measurements and weld it to the inside of the new exhaust tubing to maintain back pressure? The only reason I'm chiming in on the topic is because I'm cutting the old cans off my 82 and putting some bevel tips on. Having something like the setup in the picture I am attaching.

Couple of thoughts....if your stock pipes are still good, you might check out ebay, a set of good stock pipes bring good money! Then you could purchase some nice shortys, and some headers, and have some change left! It would also make another happy winger somewhere.Another thought, if you've never heard a wing with straight pipes (I don't mean YouTube), or better yet rode one, you might be sore disappointed if you plan straight pipes without a plan "b"- that thing is abnocchusly loud!!!(that don't look right...) abnocchusly...????

Oh...by the way, I'm running a set of off road Harley cans, and I don't have any of those problems. Hey, I have a set of '74 sporty shortys in pretty good shape I can part with...shipping will cost more than the shortys.

Obnoxiously loud. I think all straight pipes should be silenced :!: :roll:

I had considered that approach but honestly the chrome is so rusted in places and the headers themselves are having pinholes form so reselling without welding, grinding, and powder coating them is a moot point. I'd spend more than I'd make. The noise levels do concern me a bit though that was another reason I was thinking baffles would be a good idea.

On my 79 I installed Dunstall slip-ons and they really weren't very loud at all. Different than the factory muffler assembly, but not loud.
