. Sorry as you can see this is my first BMW.
Going to a muffler shop and getting generic Magnaflows fitted will probably run you about $300-$400. Buying a Supersprint, will cost you $700-$1000 (not sure, check supersprintna.com) for the muffler ONLY. They aren't hard to install, just put your car's rear on ramps.
However, if you have to cut any pipes, get the proper tooling. Do not try to cut those steel pipes with a hand saw. I learned the hard way over 8 hours.
If you're just looking for sound, I still say, save your money from the intake. The biggest sound difference you'll get is from the muffler.
On the matter of loudness... that is sooo subjective. I think my Supersprint on the Z3 is quiet and only loud when I want it to be (>4000RPM)... but my wife thinks it's loud even at idle. To me, it's just a deeper at idle. She's not so excited to ride in the Z3 these days... but she won't let me carry a female passenger in it. hispanic women...
