Is Dinan still the leader here or are there better companies now? It's been a while since my e46 m3 days and haven't been following the trends.
The only mod on the car right now is a Eisenmann Race exhaust but plans are to add coilovers next 
Anyone who has these mods please chime in here....

The Eisenmann is a good start.
Macht Schnell has both Power Pulleys and Performance Filters - quite a few M3 owners are running the setups and are very pleased with the results.
