Cat removal from 2010 UC, which method
Question regarding cat removal on 2010 UC. I have seen two different ways that cats have been removed and was wondering which way is best. I have seen the pipe cut completely in half in the mid section of the cat, cat removed and re welded. I have also seen a bottom section cut out, cat removed and rewelded. I was wondering which is the best method for my 2010. My concern with cutting the pipe completely in half is remounting the exhaust in the original mounting holes. Is there a problem realigning the holes due to the lost space from the cut?

I'm getting ready to do this very thing. I don't see how you can get all the CAT material out by cutting an access hole. I plan on cutting it in half and then having it welded. You are only cutting about a 16th of an inch of material out, just enough for the saw blade so I don't see that as a concern. I'm buying an extra head pipe just in case I screw it up or if I need warranty work.

Save the cat head pipe (In case you have to go back to cat for some reason such as EPA Troubles) and purchase an aftermarket 2-1-2 headpipe would be the best avenue to go with.

I am keeping my stock pipe and buying an extra stock pipe. I cant see spending $450 on an aftermarket one when I can buy a stocker for $125. I'm sure the aftermarket one's perform better but I can spend $450 for something else. Like a PC V and a/c. I already have the Jackpot Dyno tuned slip on's.

One thing I am confused about is Fuel Moto's Dyno charts. They show a 2010 bike with the Jackpot mufflers, a/c and PC V putting out 79.35 hp. Then another chart shows the same set up with their head pipe cranking out 79.27 hp. I don't get it. Looks like the stock head pipe performs better.
