Removing your CAT
You will need to take your expasion chamber off the bike (see manual if you dont know how)
You need to cut your expansion chamber open where this fella is cutting it and where the white
Once you have done this you will be able to remove the CAT
Thats it really, dont know too much about it because I havent done it... Just weld your expasion chamber back up with the CAT removed, give it a respay (heat resistant of course) because they tend to rust like hell even if you dont ride your bike in the wet.
The expasion chamber doesnt really have anything in it anyway if your thinking this was too simple. Literally just cut it open, remove the CAT and weld it back together.
Some exhausts also have a recirculation tube that goes to the air box. You just have to cut this off and weld it up and seal up the air box.
The snorkel in the air box can be taken out too, this will let some more air in slightly and make your bike sound a lot better. Just pull the rubber out the top, or you can cut the part that sticks out. This shouldnt affect your jetting since the bike is not jetted correctly from standard anyways. If you want to be sure stick a bigger main jet in (121 on a 28mm carb). Do a plug chop to confirm.
