Anyone on here chop/shorten exhausts?

I did a search but came up with nothing.

Was wondering if anyone on here has experience on shortening/chopping exhausts down? Im looking to shorten 1 of mine.I saw some half vids on youtube but I dont think im ready to take the risk of up a Yoshi pipe.

Examples

PICT0145

If anyone has a lead,let me know.Thanks,

-Alex

Its really not that difficult but I do recommend you ensure you have the basic tools to do it.

Is this a factory slip on(needs to be welded) or an a/m slip on w rivots?


We posted up several builds in the past on this site.

All its going to do is be irritating, and cause hearing loss. People will still try to kill you.

Here is an old pic of when I did mine myself. I will say it slowed the bike down quite a bit. I know they were stock cans but it made a difference. It was a lot louder. I've done a few things to it since then.

ya alleykat you got the basic idea. it really isnt that hard. you'll need to find a rivet gun and buy some blind rivets of course. pretty cheap mod

I have a chop saw, but I don't recommend this way as I have done this recently. Unless it is an abrasive saw it will snag and then you have to reform the areas that caught it's not hard but requires a hammer and dolly. Plus the sound batting snags a bit during a straight through cut. Not only that but the perforated pipe in the middle will need to be cut to an inset with a dremel to accept the cap again so it's almost easier to tape the shell, draw a line and cut it, then remove the sound batting to cut it, and then cut the inner pipe. Re-assembly is easy after that (I have rivets and a gun).

I did it on my old track bike. It wasn't that difficult, but I learned a few things.

Even with the packing in my 10" FMF was loud as - even on the track with ear plugs.
