Not sure how I missed this. I’m waiting for my smog in the fall to put headers in. I know I’ll get more noise and rasp with headers (or I assume anyway), but right now it’s really bad considering I’m not stock. Volume is barely louder than stock and there’s less rasp than stock. Can’t invest in an entire exhaust right now unfortunately.
I’d wait until you get the headers to do anything to the exhaust. It’s going to be much louder. The stock ZHP exhaust sounds pretty damn good with headers IMO

If you’d settle for N55 it’s probably relatively feasible. Integration of the CAS has been proven to integrate with E46 body electronics. The E9x cluster I hear fits in the E46 housing relatively well. If you grab the automatic, the transmission computer for N54 was integrated into the transmission, I’m sure it’s the same for N55.
I love thinking of unique projects like this. My wallet is the limit.
