I have a bmw m3 e46 343 hp and would like to know how can i bring up the horsepower without installing a turbo, supercharger, or nitrous? What can I do? and how much hp can i gain?

Put a cold air intake and a full catback exhaust and some nice header such as comtech or dc ...all this might give u about 15-35hp in about $2000...

Well, you can always install a brand new exhaust system. That will boost your car up a couple of horses.

Reprogram or replace the cars computer. theres plenty of aftermarket ones and they can give some nice gains in power and fuel consumption. although you'll have to get a performance workshop to reprogram the computer for you. it can be costly though.

If you are not already using these products, change your air and oil filters to the K & N brand. Their air filter is expensive, but it is cleanable and will improve horsepower somewhat. Check K & N's website for more detailed information. I also use Royal Purple synthetic motor oil which will also increase your horsepower
