Finger Wood Red Material property Tints and shades


Gentlemen and Ladies:
Buy a 12" hole saw extension, grab your 1 1/4" hole saw, get your drill, save a $1000+ dollars (I'm Canadian, it all costs more up here) and change your bike from a lean mean machine to a straight-up mean machine. Wow! The low-end rumble is to die for. The bike sounds OK to good when it's stock, but 2 holes in both stock pipe baffles and it sounds fantastic. And the good news is, your neighbours (see, I told you I'm Canadian) won't hate you unless your revving hard.

Things I found / considered:
1. Two holes and it's basically a straight pipe. I read about someone cutting 3 holes and I'm not sure why (unless different years had different baffles).
2. Don't bother drilling a plethora of holes around the tailpipe exit. It looks dumb and it probably won't sound that much better. Plus, if you drill the circle of holes around the exit pipe, it's very obvious that you've tampered with the stock parts thereby voiding your warranty on a new bike. I personally hate the look of it too because it has the look of (forgive me for saying it but...) "I want an aftermarket exhaust but can't afford it". Of course, it's still voiding your warranty when you use a hole saw to cut put holes in your baffles, but it's not nearly as obvious and hopefully nobody catches it if your bike is getting looked at... actually, hopefully, you don't have issues with your bike it's inaugural year.
3. I took out the baffles instead of doing a full exhaust switch because of the servo unit. Suzuki built a machine with a computer that is constantly monitoring / adjusting backpressure for optimal engine performance. It made sense to keep that function in tact so that my machine will operate as it was intended to do.
4. It takes about 2 minutes to create great sound when you drill out the baffles but a full exhaust change could keep you busy for most of the day. Wouldn't you rather be riding?

Here is my YouTube Video of the change:

I've drilled out the stock exhaust on two Nines, including the "dumb looking" circle of around the outside at the end of each pipe. I think adding the circle of holes provides a bit more rumble. However, in both cases (2006 and 2013), I think modifying the exhaust caused the bikes to sound like ATVs on steroids.

I'm coming from the sport bike high pitched whine. As my "initiation" into the world of cruiser sounds, I'm pleased. It feels powerful to me anyway.

A couple things. This has been done since 2006 with a bunch of write ups. I have never heard of a dealer failing anyone under warranty from debaffling. The holes around sound better then not in my opinion. We tape off the pipes and pray black paint and you can't even see it.

Regarding the servo unit, you simply buy a servo buddy that tricks the ecu and you won't see a light and it doesn't effect the rest of your system. Not sure about up there but we have the Magnuson–Moss Warranty Act which protects us from warranty issues.

Drilled the guts out of mine same as you did, but got a broom handle and wiggled the core out aswell..
Then welded in spark arrestors. Don't want to start a fire around here..
Much better in my opinion, but do like the look of 666s above... (y)

Two reasons for arrestor.
Over here things can get very dry in some areas, at certain times of the year. Real tinderbox shit.
After removing the baffles, I was concerned about the loose metal shavings that, when they get hot enough to burn, could eject themselves from the exhaust and potentially start a fire.
The second reason is this:
Because the exhaust is a fair bit louder than standard, if I were to get pulled over by the boys in blue and the exhaust was scrutinized, I could point out that I had made the effort to make it safe so to speak. (Also, the bloke involved in helping me on the day does the police bikes too). Brownie points might get me out of a ticket or being defected and sent to an inspection station..

Sounds like the Heat has it in for motorcyclists wherever you're from. I feel like we have it good here in Canada. Most of the cops I've encountered have bikes of their own and we end up talking shop. I did say "most" because there are definitely a few exceptions out there. You're still the first biker I've ever conversed with who's mentioned an arrestor. And now I'm less dumb.

Offroad bikes and enduro's generally have spark arrestors in the exhaust , street and motocross bikes don't.

Tempest - No real problem. Just take time to "work it around" into submission.

Joe - South Australia = Driest state in the driest continent in the driest country on the planet. I live near a place called Clarendon. The surrounding bush near the reservoir caught alight a few years back and I ride through that area all the time. The fire was literally one minute up the road and moving fairly fast. Had two light aircraft and "Elvis" the big orange wonder chopper dropping foam. Dangerous work in tight gullies filled with smoke. The roads near me are littered with leaf material, most of it Blu gum or eucalypt. Both are full of flammable oils and make great fire lighters.
Also look up Ash Wednesday, or fires in Woodside, Pinery, Sampson Flat, Oakbank, Eyre peninsula, the list goes on and I ride, or have ridden these areas in the past. I don't mind the use of arrestors an any vehicle with a modified exhaust..
