Exclamation Next Step

Ok guys, I've put 500 miles on my 2010 AW/Red M-Sport 135i now, and I'm looking forward. I love almost everything about this car, from the sound system, to the great ergonomics, to just the look and feeling I get from driving it. My only complaints are the huge power loss towards redline, this car is NOT fun to rev out, I would rather shift early, and the combo of factory tuned understeer and e-diff making the car somewhat difficult to drift. All in all it is very solid and composed, although on bumps I do feel a slight fight for stabilization in the suspension, kinda like when driving a truck with an unloaded bed, it will vibrate for a second.

But for now I will focus on power mods to increase my driving pleasure when flooring the throttle.

My 135i wish list, starting with the first to be installed on top, going in order:

Procede V3 or JB3 2.0 (Maybe with meth kit)
AMS intercooler
Synchronic charge-pipe/BOV (No leaking under higher boost)
AR Design 3" down-pipes
DP-back exhaust (Need help from you guys on this)
WaveTrak LSD
Good tires

I would really appreciate input from you guys on my list, and make any recommendation or comment that you wish. In particular, I need help deciding on a DP-back exhaust as I am not familiar with all the systems on the market. Thank you all for the input!

I would do DPs second, they are better bang/buck than the others on this list.

I would do better tires earlier aswell.

I signed up for the agency power group buy. $650 shipped is a hell of a deal. Its also pretty mellow sounding (still louder than stock, but not abnoxious), and had good gains on the dyno.

I would look around with the dp's, bb has a gb on, and with the charge pipe I would go with stett becasue it has meth bungs in it already. With the exhaust I would buy fast eddie's eissimann (1400 but sounds better than anything else and is 2300 new) and keep your secondary cats to keep down drone (only 5hp dif anyway). Get a meth kit and skip the fmic, go with coolingmist. Def get the lsd and consider Kw 2-3 or cross coilovers. Jb3 over procede because of the support and intigration with coolingmist.
