So if my calculations are correct... if you drill out the cat you are only getting the top section, not the lower section that is almost touching the front pipe.....

Hey Steve i need some help. I changed out my baffle`s on my 09 serg to your 2,25`s, the sound is great. My friend has a stock 2009 ultra classic  (Not screemin eagle) he is wanting to change out the baffle`s to your 2,25 also. I have not seen any how to`s on the stock ultra mufflers. At the end of the muffler it is an inverted cone shape,and it looks welded.
Any help from you or anyone who has done this would be great.

Thank`s
JP

I can recore his stock mufflers no problem. He will need to send them in, its a cut and weld situation.
Thanks, call me for more details.

It's a wonder that there is any flow at all thru that pipe. It would be intresting to know how much pressure drop is across the cat.

We finally got some warm weather and I had a chance to get the first two hundred miles on. After seeing these pics, I understand why there's a sluggish reaction to a quick twist of the throttle at low rpm. Thanks for showing us a clear view of the whole thing.

Struggling with the tube benders, trying it get the bends right so they fit the stock shields perfectly. The prototype was easy compared to this nightmare.
It will happen, just not as fast as we would all like.

An exhaust guru I recently spoke with suggested that breathing in or coming in contact with residue from a cat can cause significant health problems. Not sure if that is true. But true or not it might be well worth it to wear some sort of protective mask while drilling and chisling a cat. 



No heath hazzards in the cats.  However a dust mask is a good idea.

I use to work in a plant that made Cats...

It is a ceramic material coated with platnuim, iridium and a third metel.  The coating is very thin.

Thanks Dave! I have been wearing a respirator but still leaving a mess to clean up. Was kinda wondering how it could be toxic after being cooked to death over and over.
