Debaffleee's, how is it on the highway?

Hey all,

Those of you who have gutted your stock pipes, running 65-70 how's it sound? Do the high revv's make it really buzzy and annoying or does it still have a nice rumble?

I've been searching for a youtube video of it running at higher RPM's but they are all of the bike idling, or revving up to maybe 1500rpms.

I know this is all personal perference, but I have had mine debaffled (full) for 9 months now. I think they sound really good (even at freeway speeds). They do get a bit higher pitched, but I would not call it buzzy (with that I will state I only ride 65-70mph). My son follows behind me 99% of the time and he says it does not bother him, or is too loud. He says the Harleys that go by are far more loud. Now with the SW pulleys I am installing I would expect with the RPM drop, that it will be more of the rumble sound say at 55-60mph (with stock pulleys).

Okay, now I don't know if the exhausts on the 900s sold in California are different than those sold in the 49 other States. I ask this because, when I removed the baffles and looked down the exhaust it runs through a honeycombed catalytic converter. So, even with the baffles removed, the stock exhausts are not entirely open straight pipes.

I debaffled mine and thought they sounded great all around...idle,low and high speeds. had it that way for about 1 year,But wanted a louder exhaust with a good rumble so went with the hard krome classics and couldn't be happier. I have heard that certain inspections stations will not pass it with a debaffled exhaust.That may depend on where you live or your where you take it.... but it helps to have a place that"overlooks" that kinda thing

Its louder, but not too loud.

I had mine inspected last week. The guy ahead of me had an RC 1 with aftermarket pipes. He passed by one db. When it was my turn with my fully debaffled stock exhaust, the inspector didn't even bother getting out the meter.

As far as highway driving goes, I think its nice to hear the bike to know when to shift instead of guessing by how much my seat is vibrating.

Mine is not buzzy or tinny; just a deep throated sound which sounds better than stock but not as intrusive as other bikes with aftermarket pipes. When twisting at speed in 5th gear the sound hardens up quite a bit but is mellow without intrusive to me at 70 mph.

I have a clip I did yesterday from takeoff to 70 mph, but I do not have a YouTube account and the clip is 38 meg in size making emailing a problem. I've not found a way to upload that clip here. Any suggestions?

Why not get a youtube account? It's free and takes like 30 seconds. If you have a google account (like for Gmail) that works as a YouTube account as well.

Sounds just as I would expect. Can I ask what your top speed was? It was hard to tell while you were riding.

Doesn't sound half bad! I'm gonna call the local shop and see if they would hypothetically pass a debaffled bike. If I get the green light there, I'm cuttin' them tomorrow since I've got other work I need to be doing with it anyway!
