that larger, replacement magnaflow flows great. PN has 009 or 900 I used to tell the difference in there 3 in/out universal model. Used the get them for $40 shipped a few years ago, retail was $60-70? and makes the same power as any hiflow $150+ cat, dynatech ect. Was only 7whp on my gtp was it was at 370 iirc, and sounds a lot smoother. Fits, GTP, Fbodys fine it has a heatsheild on one side, but look up the side if it will fit, there like 12inch overall with a 7-8 case bulge.
edit, see you have a s2k. I’m not a honda guy but know there have bad ass exhaust systems stock. I think even the $3K “best” exhaust system you can get for that car only adds like 5whp or something stupid. Honda did there homework on them.
…off to dyno a z06 \<3 good factory exhausts

could u get a 3inch testpipe and put in the 02 sensor, in the bung, or do the spark plug thing or w/e the f it is to get rid of the code
and jus weld on a heat shield, or just get it inspected where they dont care about the cat
