Does anyone know what I can do to my E90 328i to
make it sound better? Would i need a muffler
delete, exhaust done, a tune? Also any places
where I can get this done in Los Angeles or
somewhere along the area?

Modifications to the exhaust in California can make your vehicle illegal and unable to pass California inspection. I would leave it is BMW made it and intended it to be as modding it might just screw it up.
Pops are bad. When you get older you will understand....

Who cares what the EPA or CARB says... a good sounding exhaust is important! Check out ECS Tuning for a cat-back or axle-back system. There should be no issues with emissions if you only install a cat-back, because you aren't tampering with any emissions equipment.
