Does the stock ZHP exhaust come with secondary cats? I remember reading that later model E46s had them, at least in the US. Not sure if that applies to the ZHP as well.
Also is the ZHP muffler any different from the regular muffler?

No, there's only one pair of cats (one for each bank). As far as I know, this is the case for all E46's in the US.
You may be thinking of resonators.
Yes. The regular E46 330's have a flap in the exhaust valve that opened up on higher demand to produce more noise. The ZHP mufflers don't have the flap so it's always "open" per se.Also is the ZHP muffler any different from the regular muffler?
M56/sulev have secondary cats, not zhp
Thanks for clearing that up

Does anyone know of a company that makes BMW Motorsport roundels for the hood/trunk on the sedan?
I want to get some. I know some people have opinions that it’s cheesy to add these but I like the look of them
