Hi everyone, I have a question about removing baffles. I have 2012 Superglide. I was wondering what performance and gas milage that will have? That's in advance for your help.

 

It will decrease both.

 

But it will sound great in comparison. Many do it until desire for performance and budget meet to form the perfect union.

 

Decrease both,could run lean enough to damage your engine,and it will sound obnoxious.

 

Badass

 

I'm new to this site and I have an off topic question about my 89 sportster 1200. I just got the bike last summer. Ran great had no problems. Went to start it a few weeks ago and would only run for around 30 seconds and shut off. Rebuilt the carb thinking that would be the problem and the battery is holding a proper charge. Any suggestions?

 

i have V&H short shots and sound great with the baffles in. a few people i ride with ride without baffles and they always say its loud but runs like ****

 

just quit being a Thigh Wad, you have one great bike and you paid a good price for her...

Now,,,, SPEND,,,, the money to make and keep her running and sounding Righteously. And don't Bitch about it....

 

To oct1949, didn't realize that question was being a tight wad or bitching!!!

 

I've drilled the baffles out of stock mufflers quite a few times over the years. Sometimes an older carbed bike would need a bit of jetting mods to keep from being too lean, especially after about 1976 or so. I've also drilled the center plugs out of a FI Sportster's stock mufflers. The engine runs fine, it isn't any leaner than it was before as the O2 sensors/ECM are capable of adjusting the air/fuel ratio to compensate for that minor change. Power and mileage did not change. It is a bit louder, but not even close to being obnoxious. Sorta sounds like an older XR750 flat tracker.

You should be able to do the same/similar to your 'glide mufflers. It won't do anything to hurt the engine, and will be slightly louder/more throaty sounding. Do not remove the baffles, etc., just use a hole saw and drill out the center up inside the muffler.

If you go whole-hog and rip out the baffles, leaving an empty muffler body, it will sound like crap, and may have a noticeable flat spot in the torque curve off idle through maybe 3000 or so rpm.
