To degoat or not degoat

If you degoat, do you need to adjust fuel mixture?
Are there any performance reasons to degoat?

I degoated mostly for:

A-The sound

B-less weight/heat directly under my butt and above the battery. I don't like all that heat build up under there. I actually de-goated and STILL moved my R/R because it gets hot enough on it's own, without all the extra heat underneath it from the exhaust goat.

I ran goatless for years but have re-goated for less noise.

My understanding is that exhaust mods, from degoat all the way up to Vance and Hines Cruizers full replacement exhaust do NOT require any mods to the carbs. No new jets, etc. Maybe adjusting fuel/air mixture but that's minor. It's not really effecting the intake part of the engine so it stays the same. Only time you really have to recon with that is when you ear shave and coaster.

Performance... some say if you just remove the goat (ala the "Scootworks" bypass kit, which is what I am running) then you loose a little low end torque because the pipes are not connected. But you're supposed to get a little more on the high end.

If you replace the goat with a joining pipe that you fabricate (nothing is available off the shelf that I know of) that joins to two pipes (commonly called the "H" mod) then you are supposed to get that little bit of low end power back and loose a little bit of high end.

I have not tried every variation so I can't report back comprensively, but what I took from it is that there are small changes and compromises in the performance here and there no matter what you do. De-goat is not really a performance mod. Except that it takes all that weight off the bike so you're not hauling it around any more!

It's more of an electrical mod. Gets that heat away from your battery and R/R and for that matter your tuccus. All of these components are happier with the goat gone!

Depends on what you replace the goat with. Anytime you alter the intake exhaust you need to adjust the fuel air mix. Most aftermarket pipes will state weather you need to mod the carbs. I lost low end when I removed my goat so after a few years I re-goated (severely drilled out) because I didn't want to spend the money on a H pipe. I'm not so concerned about the weight of the goat - I could lose 40 lbs for my health anyway ;-)

Is thare a performance difference after degoating?

Yes and No. It depends on weather you follow up with fine tuning your engine. Like what was already said, the power band changes - mostly due to not tweeking the carbs after losing the goat. You've opened up the exhaust w/o the goat, your engine breathes easier, sounds different, and runs cooler down under. If you get good pipes on to replace the stock, you may be very happy.

Good luck and post picts of what you have done. This is a supportive forum that will make some great suggestions and give you ideas.
