exhaust diameter

Post by hap2 »



What's the outside diameter of a 1500 (92) stock exhaust pipes at the very end?

I need to get some exhaust tubing for it.

The end of the header?
The end of the crossover collector box?
Or the end of the muffler?

What are you actually doing???

From the very end of the exhaust tips. The bike now is in a garage facing the bay door about 15' away. I was just thinking of getting some rubber (or whatever) tubing to direct the exhaust fumes out of the bay a good distance outside. I could just start the bike & let it warm, but just a bit concerned about the carbon monoxide as I'd probly have to keep it running for 5 or 10 min in the enclosed space.

I dunno where I can get used exhaust tubing for cheap, so open to suggestions.

Thank u

If you can't ride it to fully heat the exhaust to full temperature you will rot out the exhaust from the inside out.
The cold exhaust metal gets hit from the hot engine exhaust gases causing condensation in the exhaust system. Idling will not burn off that condensation. Only start it if you can ride it for an hour ride to get to full temperature.

You'll have to measure yours as we don't know if you have the stock or accessory extension on them.


Pretty easy to find hose online.

If the door is open you will be ok. The catalytic converter will get rid of most of the carbon monoxide anyway.

There's no catalytic converter in a GL1500.

Ooops, you're right. Was thinking of my other Honda. I should know too, been trying to get the exhaust to move for the last three weeks so I can change the rear tyre!

At one time you could buy exhaust extractor pipe. It was a flexible hose with a rubber cone at one end si it would fit over different sized exhaust pipe. Try garage equipment websites. I don't remember it being cheap.

15 feet? You can get flexable exhaust tubing, but if you get 30 feet or more, not super cheap. Might use shorter pieces, a y to get 2 into 1, then run a single line out under door. I think you're gonna find the chrome tips about 2" OD or there abouts, but inside the real tips coming out of the mufflers chamber is closer to 1" or 1-1/4", so a single 2+" OD stick of pipe laying across floor should do.

Check Hardware for water pipe prices as well, exhaust/muffler shops for pipeing or Y, Advance auto for the flex pipe?

Hap2 , do you own a measuring tape? It's the only way to be sure you get the correct size for your needs. 8-)

Use a small fan, say 15-20 inch and just open the garage door enough for the fan to blow out. It will ventilate the garage. Something like when a fire department uses a fan to remove smoke from the inside of a building. I do it all the time.

I think you're overthinking this, why not just set the choke as needed, start it and let it warm up for a minute or so and then ride it easy until it's all warmed up? Or maybe start it up, wheel it outside and then do a pre-ride check while it warms up .....

I can do, but as I was saying, even 2 or 3 min of gentle idling can fill a limited space place with carbon monoxide I don't need, but thanx for the feedback anyway
