I used to drive a 2002 E39 M5 with SuperSprint full exhaust. Then the day came last May when I had to get rid of it and go with the E46 M3. The E46 M3 is fantastic. I can't stop driving it.
Already since May I have installed the following mods:
Active Autowerke Stage 2 Supercharger
Agency Power Headers
Random High Flow Catalytic Converter
SuperSprint S Pipe
Agency Power Titanium Mufflers
The car is SWEET. I find any excuse I can to drive it too. My wife hates it, she thinks it's weird that I'm so in love with my car!
I have the following Mods coming up:
3.91 Differential
Dinan SMG transmission software upgrade for 3.91 diff.
I must say it was fun to be on the forum with such great members, but I'm not an active member on the M3forum.
Supposedly there's a BMFEAST October 4, 2008 in Flanders New Jersey. Would be great to see some of the M5 guys there!
