New to the GS I was just ok with the sound of this bike. Been working on this thing for a couple weeks and every time I felt I couldn't hear or feel the engine as I have on other bikes. I didn't want a straight pipe sound and I don't want to pay for the fancy slip ons or equivilants so I read through all the posts on drilling holes and decided to try it. I can remember dad years ago knocking out the baffles in his old honda with a punch & hammer. Didn't want to whack away at this bike and am concerned about losing valuable back pressure so I started by drilling 2 5/16 holes in the baffle. This created a phhht phhht sound that resembled a muffler with a hole drilled in it, not what I wanted. But I could also hear the beginning of a suzuki purr hidden in there under the sound. I drilled 1 more. Getting better, No rumble by any means just a better presence of the sound of power. I ended up with a pattern of 8 5/16 holes that produce a nice purr. Not obnoxious enough to rouse the neighbors but it now has "presence". At 6K RPM it sounds perfect to me. I can now hear the engine better but I'm not blasting a concussion barrage out the back of my bike. This is just what I wanted and am very happy with it.
I was thinking of doing the same. Can you take a picture of your mod, and even a sound clip? thanks, you would be helping me out.
me too :)
Stefman, batteries in digi cam are dead, I'll charge. In the meantime no way to produce soundclip but if you'll PM me I'm more than happy to take a phonecall & I'll let you hear it if you wanna do it that way. Pics by tommorow morn.

Does anybody know if drilling holes in the muffler affects the performance of the bike besides sound? :dunno:

Those sound clips on there are useless. lol.
Stefman I PM'd you...
Bluebelly, I have noticed no real difference in performance only a better sound to judge my engine by.
I think you might maybe lose a little power but not a whole lot, I could notice a little difference between my stock and drilled pipe when I swapped them out.
Pictures? plz
