Recently my car was in a crash and it has been getting its face fixed for the past 2 weeks. As I have been waiting I thought it would be a good time to buy some goodies so I purchased the double slat gloss black grills with the M stripes (without M5 logo) along with the CF rear spoiler.

Now, I have had my eyes on an exhaust modification for a long time!
I want to product a sweet burble and not something annoying and loud, what would be the best way to go about this if I was to spend no more than $1k? I am trying to not go overboard as I might trade up to the M550xi in about 12 months time.

I will also be getting a rear CF diffuser to mach, and maybe a CF front lip.
