328xi help - Headers/exhaust/tune

Okay so I'm looking for three things and thought I'd be conservative with just one thread

07' 328xi e92
1. headers- I'm looking to replace my headers, and I'm looking for the best bang for my buck! I know some of you guys have replaced your headers and I'm looking for the best options

2. Exhaust- I'm looking for a new exhaust as well, I'm see a lot of posts from ActiveAutowerke and haven't heard much feed back (probably didn't look hard enough) but supposedly their signature exhaust is very well made and will produce a substantial HP Gain.. Supposedly.. However I have heard substantial things about the BMW Performance exhaust, a little pricey but people recommend it.. Any opinions on those or other recommendations?

3. Tunes- again I just saw a thread by activeautowerke about their stage 2 tune and they're saying they have a pretty good HP gain, is there something better that anyone has tried and recommends?

Sorry for this long post but just thought you guys who have used these items personally could give a good recommendation

good luck on your quest. Just be aware on diminishing hp returns on $ spent.

1. headers options, ranked in approx cost hi to low
Supersprint, ARMAspeed, MMW, MXP, diy cut out cat
User mapleridge is also working of a new set

2. Exhaust- you will se gains if you remove the secondary catalytic converters. Other options are mostly for looks & sweet sound.

3. Tunes-
AA has one tune,used to be called stage 2
Othe companies are Eurocharged, OEtuning
They are all kinda equal for a car without the DISA manifold based on all dynos

have an exhaust shop fab you up an exhaust. You should be able to do it for half of what most of the pre made systems cost.

del 2nd cats, larger dia. piping, better flowing muffler and your GTG
