I want to put an aftermarket exhaust on my new BMW 2008 M3 convertible coupe. What kind will give it a deeper sound and make it sound mean?
Congrats on your E93, that’s a mean car you’ve got there.
Currently the only E93 exhaust I know of is the Active Autowerke system. It’ll run you about $2,700 for the whole system, plus assuming you want the software to let it run at it’s full potential it can be more. It’ll provide somewhere around +15hp more than stock, it weighs 12lbs less than the stock exhaust, and it gives it that beautiful Active Autowerke sound. It will probably void your warranty, though. I’d wait a few months for the price to go down and more options to come out, though.

How can I make it sound deeper without putting a whole exhaust system in? I heard if you do somethin with the flap it makes it sound deeper? How do you change or move the flap to get this sound?
Reasonated exhaust tips. = Have a metal panel on the inside with alot of small holes.
Make sure the tips are not too large, or you will get a "rice effect" …smaller diameter like 2 1/4 -3” is the most you should do. anything more makes your car subject to ridicule. As for an awsome Muffler switch without paying a ton of money, the "Raptor" By Flow Tech is a very cheap source of growl for your car. Just requires an adapter into the inlet side of the muffler. You would be out,maybe 45 bucks for installation and purchase if you get the Muff. from O’riely’s and have a respectable shop to do the work. FYI- All the high dollar exhaust systems are a waste of time unless you are doing it all for "show". There is no drastic improvements in power, just a name tag,and maybe a sound you like.
Be creative with your exhaust. It is a difinitave part of your personality going into the car. people tend to forget that these days.

Okay I’m buying a used BMW e46 330i (preferably with sport package) in the next two months and wondering which exhaust system would provide my car with the best exhaust note and performance .My budget is around $1200 and I favor clean, deep racecar tones, not the raspy, obnoxious ricer tones (if that makes sense). I live in San Diego and I’m not familiar at all with the cities emissions laws, but I probably need a system with catalytic converters (maybe high flow cats) and I’m not sure if resonators are needed. If anyone has had experience with BMW exhaust systems your response would be greatly appreciated. 
Some of the systems i have been looking at are: eisenman, remus, borla, AA, Supersprint, DINAN, and Rogue Engineering.
Thanks for your time!!
Yes very decent car,
For me in terms of performance/appearance/sound
-UUC
-Eisenman
-Borla
-Remus
Problem with some of the systems on a 6cyl is they sound a little buzzy, UUC tends to have deepest and most aggressive tone, with a little bark on downshift.
Best installation in my opinion would be full system – catbacks, leave stock cats in place.
All of these systems will be 50 state legal (catbacks).
In due course if you do a performance header installation will improve the complete system and set your car up for more power on the intake side if thats where you decide to go.
Youtube has sound clips, and that would be a good place to start perhaps.

Car seems fine when driving no obvious reason for light coming on can anyone help
What year of car?
What’s the specific problem: You have a warning light on (if so, which one), or you believe there’s a problem with the engine’s exhaust valves or with the emissions system? Which one, and why?

i wonder if there are any big differences between the last part of a BMW E34 (525) exhaust part when it come to a automatic or manuel gear box or touring and ordinary one?TY
I do not believe so. The exhaust has nothing to do with the transmission and vise versa.
