Concentrate on suspension, like lowering it, and looks. Horsepower mods are minimal and wont get you the babes as much as looks. Oh and go to a high performance driving school before you test yourself on the street and smuck it out.* ghead
are you smoking? If he were to apply the mods as described above hp gains would NOT be minimal. Not in the least. I'm sure him and his dad are going to mod the car so he can pick up chicks As the car is it looks good, no need to go crazy buying clears and all that. That can come later. It's not like the car is ugly as sin.
But hey, who am I to say anything. Maybe he wants more show than go ....
I dont smoke. I guess one mans minimal is another ones maximum. Exhaust is a good mod if only for the sound improvement. Funny how some peolple think its going to give you 30 hp.
used If you do your research you will find 7hp gain for exhaust is normal. I hope you dont beleive the chip sellers claim of 20 hp gain. Like I say the most rwhp gain over stock with all the normal mods will be less than 50 hp. Many people have posted dyno charts to show this. Go to some other bmw forums and look for yourself.

First of all, read the whole post. If you change the exhaust from cat back you get minimal improvements, yes. HOWEVER, if you change the EXHAUST SYSTEM, which includes the intake, the headers, the cats, the cat back exhaust (all of these being high-flow or free flow pieces), and "chip" it you will get noticeable improvements. I don't care how free flowing the cat back exhaust of the BMWs are, they are still restrictive. If you get a well matted SYSTEM, that is stepped across the board from the headers back you will expell exhaust in a much more effective and efficient manner.
Let's ponder this for a moment - many people swap out their non M cat-back exhaust for an M cat-back exhaust. Why? Sound mainly, yes, but there is also an improvement in exhaust flow (try and look up what exhaust gases/pulses are. It'll give you an idea of what back preassure is and how it works) which equates to a slight gain in HP and torque. I don't quote specific numbers because I agree that there is no way to guage (unless you dyno afterwards) what the actual gains will be.
After the system is replaced, if you don't "chip" the car you will not be taking full advantage of the mods (this is actually true for all those mods, changing your intake will make it louder but not gain anything, or at least very minimal. "Chip" it afterwards and it will make a difference because the ECU then knows what the actual volume of air being sucked into the intake is and it will adjust accordingly).
I'm not saying you'll gain huge amounts of HP/torque by making those mods, I'm saying you will get noticeable improvemtns. That and you will get better gas mileage, better response from the car, and you'll run more efficiently.
