LOUD 4into 1

Does the Vance and Hines header for the kz650 have anything other than the stock baffle ?? Maybe I'll check their site, wouldn't mind looking into a middle of the road baffle.

Thanks everyone for your replies. The first time I heard a Z1 900 I was just 14 ( sounds like a song ...and could be made into one ! ) A neighbor next door had just moved in. His bike had a Kerker 4 into 1 no baffle. The first time I heard it - it was like a drug had been injected directly into my brain. (I'm guessing that's what a drug into the brain would be like ). That day I told myself I would own one some day. And the rest is history. As for the baffle it is only a cone ! possibly missing the tube that is usually wrapped in packing? Don't get me wrong I love the sound. The problem is it is literally making my eardrums ache like heck. I tried different helmets, ear plugs ( two different kinds ), riding positions, cone baffle in. All to no avail. I have owned and ridden other Kz 1000's with un-baffled 4into 1's plus other bikes no problem. ONE LAST THEORY ! The pipe has been around awhile. The walls of the down tubes are thin ( they were rusty and I sand blasted them )and it's just letting more sound out thru the tubes.... PICTURES OF THE OFFENDING GIRL.

Does it look like this? Mine is the race baffle and it's loud but not abnoxiously loud, only when I'm really on it. It's quiter than most H/D's.

I use my pipe like a horn, If I see a prob ahead or around me I goose the throttle and they hear me and I get there attention.

I run my kerker wide open and love it loud, really not loud enough for me.

The bike really runs better from 8000 to 11,500 without baffle. I run it wide open in the city and the cops never bother me. I had a cop ask me to pullover so he could look at the bike.

I asked him about loudness of pipe and he said its not the loudness of the pipe its the riders looks (if you look like a crack head, punk or trouble maker) you will get the extra attention.

Also if you are being dangerous for the traffic conditions. He said its really not louder than a Harley open pipe. Who knew...... :laugh:

Loud pipes are a JOKE! Unfortunately, the joke is on all of us. You'd do a lot better to take a safe riding class and learn the correct method to command presence and attention while out there on the road.

In the 2 times that I "interacted" with a car in my 40 years of riding, I learned that a 500 pound motorcycle doesn't command anything when getting hit by a 4000 pound car. :blink:

Commanding Attention and Communicating Presence and Intentions is what you do to avoid "interacting" with a 4000 pound car. Neither of these skills involves loud exhaust systems.

The baffle is just a cone with a 2" inch hole in the middle that mounts just inside the end of the pipe ( the end of the megaphone ) I will try to upload a picture. Nice bike by the way !

Here's the baffle I run in my V/H sidewinder.

outlet end.

other end I drilled hole's till I like the wat it sound's.

Have no idea who made it was in a pipe at a swap meet.

Sound clip from when I pulled the baffle
this morning at about 34 sec. I pull the baffle out.

Uncorked drive by in the parking lot you tell me?

Hey Dave,

That's nothing compared to some Hardleys I've heard around here. Still it's louder that I'd want to put up with day in and day out.

Don't get me wrong, I like the sound of a high performance engine. My 1300 with a DG six into one sounds like a Ferrari once it gets to 7K. But in town no one would notice the sound at all. A couple of years ago I noticed it was gettin way SHARP. When I pulled the baffle I found that most all the fiberglass packing was gone. I repacked it and now it's loud but not sharp. In my GD system the baffle is straight open at about 1 3/8" diameter. The fiberglass goes around the baffle and deadens the sound without restricting the gasses.

I've already cracked open a cold one so any recording will have to wait for another day. I'll ask my wife to video a wide open pass so that you can hear how a Kawasaki Six sings. I'll post it here.

Regards

Bill

That baffle looks a lot like the one in a Mac I have. I removed the inner pipe and just kept the outside end cap with the short pipe attached.

Bill it be cool to hear it.
I don't ride it often with out the baffle
other then the drag strip like
you said it's just to loud.
I'll get a WFO drive by.

Wayne I've been told it's a Mac.
dude had just the meg and no idea what it was
I bought the whole thing pulled the baffle and
gave the rest back to him

I just heated the muffler and took it off of my 1980 KZ1000 LTD. Then I knocked the stock baffle out and presently ride it without a baffle. I love the way it sounds, but I will have the 2" medium competition baffle here on Friday. They also make the 2.5" baffle which is huge.
