TOPIC:

You can build a baffle for your pipe. I had to do that with mine after losen the orginal 1. called hooker header and said they quit making the header for my bike in '85 or so off to experminenting and finding dimentions I made mine out of stainless and sounds good. nice and quite when cruising but opens up and TALKS about 5500. Running and open can will get old real fast (too f@#Nin LOUD)AND i LIKE LOUD but after a coupl hrs of it screaming in your right ear you would wish it was quite.

How do you build a baffle?

I don't know how you do it but you're so close to her real image it's scarey. She is this Granny Clampett doppelganger. She wore some combat looking boots with a sundress. Her daughter (ex#2) was a total opposite. OR so I thought until she walked in with a mowhawk and nose ring. She has ditched both now and has returned to the land of the almost normal. NOT that I would know what is NORMAL! But.... I am chief of the lost tribe of the Wherethefu**arewe's and comptroller of the "Sphincter of the Universe"!

Sorry about hijacking your thread kzmarvo!

Somebody tell this guy how to build a baffle please....

Okay, since I've run amok and generally made a mockery of things as usual, I'll step up.

As always, there's two ways - the easy way, and the hard way.

The easy way is to get yourself a hunk of perforated diamond-plate steel, have it cut to a circular pattern to fit the end of your pipe, with a couple of tab extentions to be bent over and drilled for bolts. Usually, there's a rivet hole or two near the end of production-made cans that held the original baffle in place. Arrange the tab extensions to fit the rivet placement, and you're outta there.

Just enough back pressure to be effective, and opaque enough to fool the odd Barney.

The "hard" way is an extension of the easy way. Get a second piece of diamond plate of smaller diameter that fits the tapered inner of your pipe. Get a hunk of 1-1/4" to 1/1/2" steel tube about 6" to 8" long and drill a pattern of holes in it 3/8" to 1/2" in diameter. Weld the tube between the diamond plates so it looks like a tapered spool:

Excuse the crappy ascii..

Slip the contraption into the end of your pipe and bolt it in place with the tab extensions as per the easy route.

Eeeeek! that *is* crappy *ascii*!

[addendum]: Make sure that the inner (up the pipe) perfed diamond plate has about 1/4" clearance between its O.D. and the I.D. of your can - otherwise, when you fire it up, it's gonna sound like you go a swarm of pi$$ed-off *Keeeler Beez* up there lookin' for a target...

Viola!

for 35 bones, MAC will send you a nice chrome canister w/ baffle and mounting hardware. just make sure you have a collecter with the correct inside diameter
