Like most of us I've been wanting better exhaust sound out of my stock XC(damn, I wanted it to sound like a big V-twin should....) but have been hard pressed to come up with enough play money to fund a new exhaust or even mufflers. Also I am under strict orders from my wife not to make the Vic as loud and annoying as my HD was... I have been pouring over the threads on DIY exhaust mods and de-baffling but do not have the tools or skills to tackle that job correctly. Last night I had a brainstorm while looking at a pic of a gutted XC baffle...Essentially the end plate(or entire baffle) is being removed to un-restrict the exhaust flow. I reasoned that opening up the end-plate would have the same effect and could actually be tuned to a desired sound level by how many holes were punched in it. This morning I took the bags and end caps off, then started drilling the end-plate. I'd punch a few holes, start the bike and listen. Even after the first few holes I could tell I was on track.....it was sounding right. I drilled more and opened the holes, until I was satisfied with the sound. I hit the ends with some high heat black to prevent rust from starting, then put the caps back on.
I rode it for about 150 miles and wow! too me the new sound completely changes the personality of the XC. Its got a nice idle thump, a great decel. rumble and growls more than ever under throttle....best of all there is no "drone sound" at speed, I can still clearly hear the radio and wind. The wife should be happy....
This is very simple to do, the mufflers do not even have to be removed from the bike. The only tools needed are a power drill, various bit sizes and a 10mm wrench or socket.
Here are some pics at the start and painted finish. Hopefully, the vids will post(although they do no justice to the real world sound). First is the stock pipes then completed with the caps on.
**As for tuning, I have no comment on how or if this mod will effect a stock tuned bike, I have a Cobra Fi2000 PowrPro installed with the air dam out, after a few miles everything seemed to settle in and it pulls like a bear. Can't wait to change over to a high flow air filter.
