Just drilled 4x 3/8" holes through the end of each slip on. It was too quiet for me. Sounds good now though! Recommend it too any one who wants a little more rumble to there pipes.

how much louder did it make it? Did it affect how it runs? Mine are pretty quiet until I get around 3K. My 2001 deluxe sounded better I thought...not intrusive at low speed but at highway speed people knew I was in their blind spot.

Got any pics of what it looks like now?

I did that to my Kawasaki and then was told that it can cause damage to the heads over time. Anyone else hear anything like that or was the dealer filling me full of crap?

I put a pic in my gallery, can't figure out how to post on yet? Mine was also too quiet at idle but now it's just about right. If you want it louder drill more holes. I actually was considering changing pipes till I did this, figured what the hell if I still don't like it Ill change. My buddy put 8 holes in each onhis M109R a couple years ago, that's where I got the idea from.
It's really no different then changing a baffle out in a pipe, I heard that riding with no baffle would hurt (no back pressure) but don'tthink there's much truth to that,What about drag pipes...

Here's the pic. It looks pretty good almost like it came that way. You've given me something else to think about now.

If you want louder and deeper with Stage 1 slip ons, then read on.

First, remove your baffles. They are really long and extend about half way up the entire length of the slip on mufflers.

Next, use an air saw (hacksaw will work, but take a long time), and cut the baffle down to where the inner chamber comes to the outer one. Sound will be much louder and deeper.

Performance is better as well.

This is a trick used on a lot of bikes but this still took some guts to do it here. First time I've seen it used on a Vic.

Please keep us posted on the results.

You should have two screws in the end of the slip on mufflers. They are usually hex.

If they are there, then you have removable baffles. Most are removable, but just removing the screws won't get the out... You will need to use vice grips or a puller to get them out. They are in very tight and the more you have ridden, the harder they will be to remove, due to carbon build up.

I read this the other day, so today I drilled the 4 hole thing. It sounds fantastic. I would keep it that way, except I don't like the looks of the stock pipes. I want the radius curved one, I hope they sound this good.
