Finished The Bafflectomy

I just finished the Bafflectomy on my 919 today. Man it sounds much better than before. It wasn't as easy as I thought it would be. Than center pipe was a pain in the A$$ to remove. I'm very pleased with the final result.

Sounds more like a 919 should now, doesn't it.

It's a fool who looks for logic in the chambers of the human heart.

I did mine a few weeks ago, love the sound, I only had a cheap cordless drill at first so it was a 2 day affair, I went out and got a normal drill and it took all of 30 mins after that. minus sanding and painting

I did mine a couple of days ago. Sounds awesome, I love it, it doesn't sound like anything else out there. I plan on taking some video to give people an idea of what it sounds like.

Here is the end baffles that we drilled and beat the sh*t out of, you can see the tack welds on them:


Here is a picture of the pipes, I had the flash on, normally you don't see so much in there:


Here flash is off:


Here is the inside of my right pipe, you can see the bent, deformed metal on top that took a beating, this is the part the end baffle is attached too:


Here is the left pipe:

This is the bafflectomy according to this:http://www.project919.com/members/ho...afflectomy.htm
Much props to PerfectPower, sweepUK, Sniper, motocycho, Don I., ratdog, Typhoonblue919, Skipman, wphistory for making that.

You can take all the insides of the cans out, SweepUK has done that:

Here is a link to what SweepUK has done to his pipes: http://members.lycos.co.uk/sweepyuk/...20debaffle.htm


I think that taking all the insides out would be pretty hard. Trust me, it is plenty loud the way I did them, it sounds so friggen awesome, I wouldn't want to go any farther.

Just to add, with the perforated stainless tube and baffle packing it is no louder than other aftermarket cans. Mine sounds very similar to Scorpion cans. I will take a better sound clip of mine soon and you will see.

bafflectomized since 2003... still loving it.. IMO its a complete waste of time and money for anything more.


I love watching the new guys post... wondering what we "oldschool" 919 owners already know about the bafflectomy.


motorush seems like since a distant memory already.

think i'll just leave mine alone to keep it legal. however i have a hole poked thru each of the cans.
the opening is just too obvious illegal mod.
time to save cash for aftermarket pipes.

Just about all aftermarket exhaust systems are illegal too. For both noise and emissions.

Yes as SSS says it makes no odds, may as well rip your cans apart! You could do what I did - pick up a set of reasonable second hand standard cans to butcher so you can use your nice standard ones to go back on the bike if you don't like it or sell the bike.

I will get a sound clip done of mine this week so you can hear mine properly.

All of those companies you mentioned only make "off-road" exhausts. None of which are technically street legal.

If it were legal, it would be just as quiet and restrictive as stock. Some companies make cans that are legal as to how much noise they make, Arrow comes to mind, but they still don't meet the emission laws.

It's not a big deal and you won't get a ticket in the US, but you technically could get a ticket.

Edit: I just noticed that you're in singapore. So I have no idea what the laws are there. It's possible that they are perfectly legal there.

Seriously....why bother?? If you just spend the dough for Sato's, you lose weight as well as gain approx 5 hp.

Why is this even an option?? Please explain.

The plod are scared of loud noises.

Do you mean why is the bafflectomy an option??? Maybe everyone doesn't have money lying around, plus I like how the stock pipes look (although Satos aren't too shabby either).

Similar results with a baffle job! Weight loss plus insignificant HP gains.

Besides, some of us have other things to spend money on, not just our bikes!

And if you really think 5HP on these bikes is worth the expense for SATOs etc, then go right ahead. There are better things you can do for performance / ride-ability on these bikes with that kind of money though!

+1; I just got a pair of de-baffled pipes and it feels like the front will get light easier.

I drilled the array of holes around the center pipe without doing the full bafflectomy. It gives a bit of growl, but doesn't upset the neighbors. Most of the people that I show it to think it is stock.

thats how mine are.. fairly quiet while just putting down the street.. whack the throttle to get onto the freeway and you get a very nice growl..
I ussaly wear earplugs for wind noise when I'm riding but sometimes go with out just to listen to my baby sing..

I believe there is one, I just can't remember where I saw it. Give me some time, I'll remember at some point.

MotoPsycho had one, but it was created at an elevation that will make it useless for most people, plus I don't think the system was set up for a proper dyno run. Something like that anyway... Basically you're kinda SOL.

Anyone have vids or sound clips of the bafflectomy or holey muffler? Most of the vids/sound clips are revving at idle, it would be nice to hear one going down the road.

Although listening to exhaust notes through computer speakers hardly does any good unfortunately.

After commuting for a couple days with the bafflectomy done, I've deemed it way too loud for my tastes...even with ear plugs!!

On a scale of 1-10 of loudness, (1 being stock and 10 being bafflectomy) where does the "array of holes" version lie?
