Catalytic Converter Issues
Hey all,
2007 Ford Mustang V6 Pony Package + Ford Racing Dual Exhaust.
About two months ago (!) I attempted changing my spark plugs (and wires, and distributor coil). In the process of doing so, I cracked the (new) plug, causing a misfire in Cyl 2. Had no idea what it was, just noticed at low RPM's I didn't have as much get-up-and-go. Didn't know it was in Cyl 2, so I took apart 4, 5, and 6, rebuilt them with new plugs, tried again, no difference, so I said eff it and took it to a mechanic.
Hence, now knowing that Cyl 2 was the one that cracked. In the process of which, I probably put >50mi on a misfiring cylinder.
Ever since then, I've had the (dreaded) P0420 "Catalyst System Efficiency Below Threshold (Bank 1)". For the most part, I've ignored it -- it wasn't really hurting anything and as far as I know the "right answer" is either A) a new O2 sensor, or B) a new Catalytic Converter (which would make sense due to putting 50mi on a misfiring cylinder).
Took my Pony to a track day this weekend, and it sure sounds like I blew a hole through my exhaust now. Really hoping I didn't scrap my muffler(s).
I've clearly put off fixing this properly for far too long.
I don't REALLY want to drop $1k per cat for an OEM replacement from Ford.
American Muscle has a few alts listed from Pypes, and O'Reilly/AutoZone/etc have FloMaster and Magnaflow.
As far as I can tell, Magnaflow is the cheap answer (I'll still have to deal with cutting and welding, which I have to do anyway due to this (theoretical) hole in my exhaust).
tl;dr Any recommendations for a replacement catalytic converter? Also, do I need two, or just one? I think two -- one per bank.
Thanks!

I originally had bought a pair of universal Magnaflows, but it would have been *more* expensive to adapt those in, than just replacing with a factory cat assembly.

Ended up buying an entire cat assembly off RockAuto for ~$270 and having the old one cut off -- something worth noting is I have a V6 with an X-pipe, so they had to do some custom work there.

Yeah but I guess for the 2013 V6 models I don't find such whole assembly.
Only a Davico part but I guess its a universal catalytic converter which you have adapt:
