2011 E93 M3 Comparative Data on Normally Aspirated Upgrades,Tunes and Exhaust

To all

I've read and searched this and other Forums. At this point I'm confused and probably will remain so after this thread.

I know induction would be a quick although expensive fix but I want to try to stay under $5,000 if possible. If anyone in Georgia knows..Please advise if I can delete the Catalytic converters or suggest a High Flow Cat Back like the Borla Atak exhaust.

USE:
1) Daily kid transport to and from school
2) Weekend Cruiser
3) Road Atlanta 6 Track Days per year

I am looking for an improved Torque Curve and less "Jerky" feel from my car.

Thanks for your help and suggestions.

P.S I like the rounded hard top versus the E92 and my Wife had input on the Convertible. I also like the "Active Rollover System"

Bruz

Tune, exhaust, pulleys. That's about it if you're not going forced induction.

You may want to check rules at the track for convertibles. Some tracks require you have a full roll cage - even if it's hard top. Cheers!

I checked. All Tracks that Chin Motorsports run at allow Convertibles with active roll over. So far the only tracks I've found that don't allow are certain Drag Strips which isn't a problem for me.

Road Atlanta
Watkins
Laguna
Etc.....

Understood. Just looking for real life experience....I've read the web sites and watched the YouTube videos.

Does anyone have comparative real world data on the Tunes,Exhaust,Pulleeys and Cool Air Systems?

I am not lazy...It just seems to be a case "What I bought is the best"

I sincerely look forward to your input.
