Best way for adding 50HP and good midrange torque

Thanks all,
So the summary is:
1. Lose weight
2. Change mufflers/cat
3. Remap
Will not give 50HP, but at least some.
I have seen remaps on rolling road (with mod mufflers) giving 15-20HP on dyno.
Then, next question, what is the best weight reductions without "destroying" the car? Battery, seats, Mufflers?
In Sweden C2S are VERY expensive (approx 70+k$)

You've received a good deal of wisdom and counsel here, albeit some of which was tongue-in-cheek,...
There are several ways to realize a 50 HP increase with a resultant bump in torque, but the first question I ask all my customers who ask about such things is: "What is your budget?".
The answer to that truly defines how you will proceed.

Here is what I did to get effective horsepower gain
took out 320#
put in a full cage
triple adjustable suspension
lowered car a few inches, a bit more actually
LWF
aerodynamics added

I can't believe this thread has gone 3 pages without mentioning Fabspeed products...he should be able to get at least 50hp by using their airbox, cat bypass pipes and mufflers.
Right????????????????????

Nope not even close.....but with mine the mufflers are not even there...weight reduction and throughput, what little there is.....

My quick calculations say that you would have to remove 450 - 500 pounds to get the same acceleration as you would by adding 50 hp. I don't think removing the carpet is going to help alot.

It's not too hard to get to the 2700 -2800# range. After that you have to make some real sacrifices in the streetability area.

Here is a list of what I removed:
- spare tire - 30lbs
- lightweight deka battery - 20lbs
- trunk carpet - 5lbs
- replaced normal with RS door panels - 20lbs
- rear seat + seat belts - 10lbs
- rear deck shelf + speaker - 20lbs
- RS carpet - 25lbs
- LTW flywheel - 20lbs
Total weight 150lbs removed. That, along with a Rennsport chip, made the car snappier. But it is still no 50hp increase.

The general questions always get innovative answers here
Let's assume budget is 7000$, what can be done? Car has 95000km on meter.

It seemed that aftermarket adjustable seats, after you add up the rails & mounting kits, would weight almost as much as the stock.
