I would have written it out, but a video is more fun.
just watch, I speed up the boring parts.

haha! you heard the tv?
I have no idea what was on, it's mirrored to the tv in the living room and my wife was watching some dumb crap.

Very cool, esp. the sped up parts. Thanks for the vid.

Would you be willing to make a few of those for a price?

mystic_1 · « **Reply #5 on:** September 24, 2009, 05:28:28 AM »

Just curious, why not use a drill bit to make the holes? Seems to me that'd save you some time.

because then I'd have to mark out all the drilling points, this way I can offset the holes evenly just by touching the edge of the screws together when they're all the way down.

also, those self tappers are sharp every time, a drill bit dulls after about 200 holes.

yes

the baffle i made is loud and low. I've noticed, the longer the pipe the higher the pitch. but if I wrap it in fiberglass it dumbs down (glasspack)

How long is the one in the video? What's the ID/OD of the pipe you're using?

It cram-fits into a 2 1/4 inch pipe, and it's 6 inches long.

i made a ride-around video to see what it sounded like under acceleration.
I'll post it when it's done.

$25 shipped

hey pinhead, is that too much?

I wanted to see what it sounded like under acceleration.

Peters1983 · « **Reply #13 on:** September 25, 2009, 11:32:53 PM »

That sounds awesome, what exhaust are you running? Any thoughts on fitting something like that to a 4-2 setup?

Pinhead · « **Reply #14 on:** September 26, 2009, 01:57:43 AM »

That's not a bad price for what's basically a custom sized and built muffler. Could you get some closer/more detailed pics of the flares and also show exactly how it fits into the 2.25" pipe? And then how is the end product attached to the header/pipes?

it's a yoshi header 4-1 with a cut down tail pipe.

yeah... make two of them.

kidding, pm me with your inside measurements to the hundredth. like (2.25)
I can't make them for megaphones unless I make them out of a flat sheet and roll em up.
too complicated to get right without the pipe in hand.
so I just don't do cones.

Nice work. Much more technical than our approach.

A few of us Duc boys took a low-tech approach and used sink strainers in repacked Emgos. They actually work and sound great:

I cut my exhaust with a pipe cutter, so it tapers in a bit then I cut the baffle down the center so it'll roll in. it just stays there.
the one in the picture is the first one I ever did. it is cracked, cause I didn't heat it first and I tried to bend it too fast.

I use a bolt to go thru a clip nut.

just to remind you , this is not a quiet baffle, it just makes it sound bad ass.

I found some perforated sheet metal at the hardware store. I'll use it to make the next one.

It's got to be a little quieter than the straight pipes I'm running.

I like the sound of my 650 with straight pipes but the straight-ed CM400T sounds like a damn Civic with a fart can. $:-\$ I'm hoping some type of baffle/muffler will change the sound. Though I may go with a pair of these...

Pinhead · « **Reply #19 on:** September 26, 2009, 08:42:11 PM »

That perforated sheet looks like it'd make the process 100x easier. Now if I only had a damn welder!

Industrial Cafe · « **Reply #20 on:** September 26, 2009, 09:31:33 PM »

i don't have a welder.

I think I'm still missing how everything is tied together...

stealthy · « **Reply #22 on:** September 27, 2009, 12:49:13 AM »

I think I'm missing something because I dont understand how you make the baffle out of 2 1/4" pipe and make it fit in 2 1/4" pipe....?

I'm sleep deprived.

mystic_1 · « **Reply #23 on:** September 27, 2009, 06:28:26 AM »

Sounds to be like he cuts the baffle pipe down the longitudinal axis and then overlaps the cut ends.

Industrial Cafe · « **Reply #24 on:** September 27, 2009, 06:51:45 AM »

I cut the gray piece in the video out of 2 inch pipe and and flared the end to 2 1/4

but mystic has it exactly- on how I've done some of them. the spring effect holds it in well that way. there is alot of trimming involved when you do the split, roll, spring, deal.
