I just did this tonight. Heres a before and after pic

...Not sure if I was allowed to post these two pics here, but I figured people would like to see more examples before they try this themselves.

 

How the hell do i get my micron can apart? theres two rubber seals and i dont see any rivets. Does it pull apart?

 

Two questions:

1) Where did everyone find the SS mesh to wrap the inner pipe in?

2) Did you use closed end (leak proof) or open end (leaky) rivets?

 

Im not sure about your micron. My vance and hines was only 4 alan head bolts. And the end cap was a pain in the a$$ to get off. It may be welded...and in this case your better off just buying a shorty or leaving it the way it is.

I just used steel wool as packing. I bought the scrubbies from sears and unrolled them then wrapped it around the baffle.

I didnt even bother to drill and rivet the cap back on. It was hard enough to get back on I dont think it will be a problem. But if it is, I will just seal it with silicone and drill and rivet it back on.

 

Can you cut from any end? i have a Scorpion exhuast that starts out blue and goes to silver... Could i cut the bottom portion off instead of the top of the exhaust?

 

I found out how to take the micron apart. There is a hex screw inside the exhaust outlet which secures the cap to the cans shell. Im not sure how i would shorten mine because the part for where the endcap screws into the core tube cannot be removed. Maybe i can take the can apart and cut it off from the bottom.

 

Its possible to cut in the center then weld or jb weld the pieces back together and then you still would have your brackets?

 

i did cut down my micron 5 inches off the bottom. i actually cut it right on the backside of the hanger so i could get rid of the scratched up part of the can. I then cut out 5 inches out of center tube then using a torch i brazed it back together. if you dont have an oxy act torch you probably cant do it. i suppose jb weld would work though

 

My pipe actually connected at the bottom so it worked out in my favor.. Looks great

 

What is the brand of muffler you are shortening. I would like to do this modification. I have a Yosh RS3 on 2002 F4i
