I doubt a local exhaust shop would partake in welding up an 'illegal' exhaust modification. NY got real strict with this stuff a few years back. Finding a local welder that will take walk in's is just as tough. I own a nice Miller welding machine, but Id HATE to get my settings wrong an blow thru the pipe and make matters worse. Drilling it and pulling it out was the most reasonable approach for me and Im quite glad I approached it that way.

Gutted Cat
I took the easy route. American Custom exhaust. Not only running cooler but there is a performance advantage. No more restriction in the exhaust. A major part of high performance is a free flowing exhaust. Look at that of crap you removed from the pipe, that hindered flow.

I checked out their website......it appears all they are doing is removing the cat and adding their own 'power chamber'.....I like the idea of affordability, but they arent changing the header pip or its bends or dimensions, so Id love to know what their 'power chamber' is.

I found a used Krome Wurks hidden header for a good deal this week. Oddly enough, I the only difference I can see is the Krome Wurks doesnt have a cat....every other dimension looks the same to me.

Removing the cat while the exhaust is attached to the bike presents the possibility of pulling some of the dust/debris back into a cylinder on a reversion pulse. JMHO but I would remove the head pipe, and thoroughly clean with compressed air, vacuum, etc. before starting after the cat removal.
