Interested in drilling or punching out the baffles in my stock cans. I've done the drill out method on my 06 Vulcan 1600 classic, that was real fun. Three plates to drill through using hole saw. Two removed from outlet side the third had to be cut from inlet side meaning you had to pull the entire exhaust system and separate the mufflers from the pipes. It was a lot of work.
Is there a write up some where that details (step-by-step) either punch or drill process for the C-10?
Thanks.

Heck I'll do it, bring it on over.

1 1/8" hole saw bit and a 12" extension. The bit will fit exactly into the end of the exhaust. Slide it in till it stops pull the trigger untill it moves forward again; repeat opposite side. All done

Yep. That's the "How-To".
I used a step drill, because it was what I had. Worked fine.

Yes sir a step drill will work just fine. One word of caution; when using the extension make sure that the bit is securely attached to the extension. It really sucks to drill out the baffle for a friend only to find that when you pull back on the drill you find only an extension. Lesson learned that day LOL. All turned out ok.

Originally invented by SISF, you do the deed (easily) w/ a 24" long rebar and a BFH. Have a friend hold the bike firmly w/ front brake. Then tap the pointed end of the rebar through the baffle. Repeat on the other side...no muss, no fuss, no crumbs to clean up. ;)

The drill makes a much neater and well defined hole. I used a 1-1/8" hole saw with extension, (the largest that will fit into the muffler)

No offense to Steve, that method seemed so.......well crude. We have come along way since the stone hammer and granite chisel. Power tools are your friend. A couple of revs from the engine blows all the crumbs right out.

I fixed it for you!

A one inch chisel and a small sledge worked just fine here. Bada bing, bada boom, done.
-
Yep, an extra long chisel & a BFH worked great here too! Thought about the hole saw method, but noticed the hammer & chisel on the bench & that it would save me a trip to the hdw store for the correct sized hole saw......

Let me get this right, if I punch a hole in the outlet side using whatever tool I have handy that is all it takes to open the exhaust?
Sounds way to simple, but it's a 12 year old bike.

Yup, just ram a pointy instrument up the out hole. Bang with a BFH. Repeat on other side. Congratulate yourself on a job well done. Celebrate with an appropriate adult beverage.

Does anybody have any sound clips of this? I am interested in doing it, but I don't want to have the bike become obnoxiousness loud. Had enough of that with my old bike which had open pipes with no baffles at all. And it wasn't a Harley. ;)

Not a real big change in the sound level at all.... The muffler is still there as are the baffles so only some of the escaping sounds get to take the short cut out to the free world.

A bit more growl than stock, but not obnoxious. I love it. Wind noise is far more of a noticeable problem for me than exhaust noise.
-
The sound is 'perfect' IMHO.
No one knows to look or listen @ idle, just a stock exhaust pipe. Then get on it above 4k and listen to the 'rip' as the exhaust opens up more space when you need it. Then back to stock for cruising thru small towns between rips. ;)
-
All right, you guys just convinced me. Time to get a hole saw. :D

I'm working on shortening a pair of stock cans.
Had to put the project on hold until school is out and I can take them to my buddy's shop in Phoenix to use his chop saw so I can get a clean, straight cut on the can.
I can tell you one thing though--the 4 rivets on the front of the can just hold on the beauty rings, nothing more.

Yes Sir, Mama K did not want these cans falling apart while riding down the road

These may be of interest on this thread. Not my pictures, I just saved them for later. A baffle-ectomy has already been performed on these (note the hole in the center of the inlet side).
-
:goodpost: :thumbs: :hail: I have been meaning to do a search to find those photo's. Thanks...
-
Baffle-ectomy surgery was a success. The C-10 came out of the OR yesterday afternoon and sounds just a little bolder now.
Found a 1-1/8" hole saw and extension on the tool box so gave it a go. Complete job took less than 8 minutes, super easy.
Now if the rain will let up we'll get her out on the road for a little test ride.

We generally rate these jobs on the beer scale.... With one beer being super easy!
-
I have the bafflectomy hole saw and extention if anyone wants to do it in NJ shore area when I'm up north.
No I'm not sending/lending just stop by. PM me
-
Just did mine. Took all of 30 sec a side. I can tell the differance in the garage, crappy weather right now so a true ride report will have to wait.
-
I attempted to do a before and after video.
This is before:

And this if after.

Please forgive me for butchering the name of the mod. My bad. ;D

Nice!
-
Mine had a partial baffle-ectomy. The PO must have used a 3/4" hole saw (i guess). I performed a full baffle-ectomy and do notice a very slight improvement - in sound anyway. More rumbly I think.
-
Anyone have definitive info on advantage to performing Le Bafflectomy? Or is it just better sound and <i>seems</i> to have more power at higher RPM? (Nuthin wrong with that...just askin)
Thanks!

I wouldn't go so far as to say it has "More Power", but the throttle response is much snapper. That slight sluggish lag is gone.
Oh.
And the sound is well worth it!! I still ride with a bunch of ZRX buddies and they have mentioned that my "Stock Exhaust" is the best sounding system they've heard.
For what it's worth. :thumbs:

Based on recommendations on this site, shortly after purchasing my Connie, one of the first things I did was the Bafflectomy. It helped reduce the buzz slightly, and perhaps increased the the throttle response. It may or may not have helped my fuel economy as well.
Mainly, however, ever since drilling the 1"+ holes in the baffles, my bike sounds meaner now...
