Thanks, look like they’re about 6 inches in diameter and perhaps 5 inches long? Can anyone confirm?

@Kracka do you get significant exhaust smell from your cats? My green cats (different car) had a pretty noticeable exhaust smell (so much that leaving it in the garage to idle made things funky). Definitely better than raw exhaust but nothing close to stock.

Nope, which is exactly why I went with the 49-state EPA compliant cats. I've run plenty of testpipes in the past, but that smell is just so obnoxious (not to mention poisonous...younger me apparently didn't care). Idling in the garage at home, parking ramps/garages, stoplights with the windows down, etc. no issues at all. My wife, elderly parents, nor coworkers have ever commented on any foul odors, either.

You will get a bad smell from cat deletes not hi flow cats !

It can, it's just not as potent. Depends on the cats.

Yup, exactly, all depends on the specific cores. There are a multitude of types and styles.
