AHH HELP, installed MAC 2-1 and it falls on its face, running out of time!

yeah, yeah it does...

I gotta ride it like this tommorow too, hopefully I can change it back tommorow night...

Also no gaskets so I need to track those down first.
 
I have temprarily ffixed it by rotating the stock exhaust mount, forcing the exhaust down, but that is stressing the mounting point at the head so not my first choice...


is this bad for the exhaust/head to have stress on it like that? If its fine I could fab a new bracket maybe.

otherwise it looks like I may need to find a 1980-81 era footpeg mount as this system may actually be for that bike, and it appears that the pegs are about an inch higher...?
 
I am goin to try packing it with stainless steel wool, the hardware store sells little rolls of them for painters.

Hoping it is stiff enough not to get pulled out the pipe like the FMF stuff did...
 
I will try, they said it was stainless, its easy enough to do now that I have tried about 12 different ways with fiberglass I'm a pro at getting it apart... :rolleyes:

Still not sure it is going to work though as minie isnt the "tube with holes" baffle its the "2 offset tubes" style, wrapping just blocks the tubes and you get no flow...

great thread though, not sure how search missed that, jeez...
 
Wrap the outside of the baffle.
The stress of you tweaking the exhaust in my opinion will eventually subside with the high heat.

So you think the heat will "fix" the stress? Just clarifying, hopefully thats what you mean :)

I'll post pix of my baffle, I tried wrapping it but you will see what I mean about why fiberglass didnt work.
 
I opened up my can today and found four coat hangers wrapped around nothing making a racket.
 
So this is my baffle, when I wrapped it it just plugged the outlet pipe and I lost 90% of my power. I packed it tight, I packed it loose, only thing that almost worked was super super loose, then it all wadded up at the bottom and was ok for a bit, then it all shot out around the rim...

I didnt have time to go to the store today (see my stranded in the rain post for details)

I did find these in the boxes of stuff my grampa had in his place in Oregon:

They are wound in a circle and VERY elasticy:

So just as a "no cost and 5 min of my time" expirament I did this:

Still should be plety of space to "pass gas" and if it takes that tinny twang out of the exhaust not Im happy.

I will let you know if this dumb idea worked when I take it out tommorow morning (I am watching the baby alone tonight and she's sleeping)
 
For the record these things would be AWESOME for you "normal" baffle folk, the fact they are like tight elastic bands would make this job a snap, just slide on maybe 4-5 of them on your baffle, no wire tie needed, bam, plus stainless, may never have to do it again!
 
That stuff will be gone in no time. Burnt off in the wind.
Ask Posplayr what he uses.
 
really? Ah well, I was just killing time, I am buying the rolled up stuff today after work.
 
So, any suggestions on how to wrap this particular baffle without plugging the in/out pipes?
 
So as far as the 5km ride to work is concerned it took the 2000-4000 buzzy tinny twang out of it. Still a tad loud for me but at least it sounds loud-performance rather than loud-crappy.

I will go for a more extended ride then post pix of how the sponges are holding up.
 
why? sorry, I am not sure what's up here guys, I used stainless steel?
 
Common Reels: The simplest form of stainless steel wool is a continuous roving, 4 inches wide on reels. This product meets all of the physical demands for exhaust applications, but is presented in a basic form requiring the muffler manufacturer to do all of the processing and assembly.


Actually anything will work it is more a matter of how often yopu want to change it. On a hp motor it could change your jetting requirements.

call me dense if you want, but who, what how huh and hmmm? Are you saying I should go buy this?

Only thing I can find are the little rolls used in paint sections of hardware stores, I have NO IDEA on ANYTHING other than this.
