How to drill out factory baffels

[ANLR21]

Brian, just go for it. No, it won't make it sound like a 2 Bros or a Leo, but it will give you a little more sound and won't set you back $700+. Won't piss off your neighbors, either, at 2:00AM. Sounds a little better than completely stock, anyway.

I used a 12" 7/8" bit on mine, took about 30 seconds for both pipes. Added 12 horsepower, 16 mpg, and makes the ladies swoon. I wish.

I would say do not do it, save up for some aftermarket pipes. I did it to my 061krr and regret it. I have since put a slip on scorpion and now want the stock exhaust back on. I like the silent stealth sound.

Please do not drill them out. Save up and get real exhaust. Drilling them out makes it sound like crap. After i bought my scorpions i drilled out the stock muffler just to see what the fuss was all about....it was horrible. Maybe my degree in music has trained my ears to hear certain tones, i dont know, but what i do know is it was the worst sounding exhaust ever.




Sorry, got carried away.....its your bike do what ever you want If i had listened to half the people i ride with i would be riding a harley right now and following the rest of the sheeple.

Oh, for crying out loud,just remove the entire muffler.

Did you remove your muffler, or leave it on the bike? I was worried about the metal shavings from the baffles getting in places it should not be. Thoughts?

Hey if you still have it around you want to loan the OEM can to me, I wouldn't mind adjusting them to see what kind of sound I could get without destroying mine.

Hey Brian
I assume by now you have the instructions, but may be hesitant IRO the sound, as was I. I started with 14mm (1/2") followed by a 20mm (7/8"), which required some force/sharpening of the masonry bits, but dont be concerned.
I've heard lots of the expensive aftermarket cans and I think this mod. sounds really good (similar to Honda 600R and Triumph Daytona 675)

I drilled mine last night, used a 12" 18MM masonary drill bit, that cost 40GBP (which is useless now), had to use ALOT of force to get it puncture through, but, hey, got there in the end, and I like what I hear. It's not a substitute for getting after-market exhausts, think of it as a 'fix' until you get some after-markets.

If you're doing it be prepared to sharpen the bit, or use alot of force trying to puncture the metal. Have a torch on hand to keep track of how far you're getting and if you're making progress.

I did this mod a while ago and posted some pictures and a little info here:

Ok I just bought a 05 fz6, I was looking to drill the baffles out. What are you drilling? I stuck a 1/2'' rod in the exhaust and about half way threw I had a wall and then stuck it the rest of the way to the back of the muffler. I did not feel anything solid to drill out. The only think solid I hit was the back of the case. What am I missing? Is my muffler different?
