Modified stock pipes for a little bit of sound (video)

Factory Sportster mufflers (as well as many other HD models) have a 2 part deal inside. One is the baffle that is most commony drilled, punched or pulled. Then there is the muffler part that is a much larger inner tube that secures the packing. To completely empty the muffler seems to be quite a task while still installed...but if you just want to pull the baffle, you may have success while still attached to the rest of the exhaust.
Honestly, I don't like crawling around on the ground. I'll pull the bike up on a lift, pull the mufflers, do the deal & put em back on.
Exactly like this...and yeah, I usually have a few onlookers.
But my main concern is the hot metal shavings from drilling the baffles that the hole saw bit will fling everywhere. They'll embed in the black powdercoated parts on the bike like frame & swingarm. They don't necessarily cause damage but they'll eventually rust leaving it look like crap after a few years.

prolly works great on non-ECM bikes without EFI ??

Last year I did an 09 Road King...no problems. The majority of bikes I do this to are fuel injected. If you have the stock air cleaner or an aftermarket one with the dealer download (or some other fuel management) you should be fine. But if they're doing all of your other service maybe they know something about your bike that's on the line. Check your plugs before and a hundred miles or so afterward. That will tell you exactly what's going on.
And to add, I make full sets of pipes for many many bikes that are fuel injected. I never baffle them. I'll "tune" the bike for a specific back pressure and that's it but that's because I don't usually run a crossover pipe like your factory exhaust will have.

Let me add this again though, modifying your pipes in any way can sometimes cause your bike to run lean. It depends on your current fueling and air cleaner. Check your plugs before hand then afterwards. If they're white (not crusty tan) you will need to add fuel. This is where you would rejet (carb) or visit nightrider.com (EFI) for the fix. Either way, it's still cost friendly.

Just did this to my 09 iron. I was waiting on my x14ieds. It took a little longer to get the outer baffles out but I'm a complete rookie and got it done. With this, your do it yourself air cleaner thread and xieds my bike sounds and runs way better. It will hold me off till I get my sikpipes I want.
Thanks for the great threads mreed.
