How to remove Brutale cat & install midpipe

Sorry if this has been answered before, but for some reason I can't find any advice/instructions on how to go about this. Some questions regarding the Brutale...

1. Can the midpipe swap be done without removing headers or mufflers?
2. How do you go about getting those springs off & on? Brute strength? Is there a special tool for those springs?
3. What and where needs banging to either loosen or fit on?
4. Any "How not to do it" advice?

Those in the know, please chime in. Much appreciated.

There is a special tool, although not necessary. Any curved pick or hook with a decent handle should do, they don't have much tension. Just pull on one end and unhook. I replaced my headers so I had to have the collectors off. As far as installing just loosen all the mounting bolts, get the pipes to fit into one another, and then tighten all the bolts up.

Great, sounds fairly straight forward. Thanks for that.

All the bolts on just the cat (or muffler and header too)?

You just need to take of the muffler nut and the springs on each side of the cat. The header pipes stay put, just remove the spings.

Thanks. Appreciate your help.

Ok, install done. Here's what I know now. I know what it means when it's advertised as slip-on, bolt-on or easy fit, it really means your entire sunday morning.

Removed mufflers to bang the cat off. Wrestled with midpipe forever to fit it on.

Here were the problems:
1. Ill fitting midpipe. See next points for details.
2. The muffler end of the two pipes of the midpipe were touching each other so mating with mufflers wasn't easy. Had to lever them apart to fit. And because they were not well aligned they had to be banged on. They still haven't slid completely over the muffler ends but maybe a ride (the heat and some more banging) will seat them properly.
3. One of the pipes on the header end was slightly oval which made it a real pain to fit. And yes, it does leak badly at the oval.
4. Can't fit the springs back on. Need to stretch them almost an inch which I find impossible. Maybe I'll buy longer springs.

Will go for a ride and see if the whole thing falls apart. Actually to be fair, it's on pretty tight but without springs at the moment. Anyway, they're on and I'm off. Ride safe everyone!!!

^^What brand, and where did you buy the midpipe? Sounds like one I'll want to avoid.

It was a piece of cake for me. Took the mufflers off in just a few minutes. the Arrow pipe came with a spring tool so that made removal/replacement of the springs a piece of cake. They also provided new springs which was a nice touch. Additionally, there was a new bolt or nut which made it unnecessary to remove the old one from the old mid-pipe. And the new mid-pipe was a nice and easy slip-on job.
