One of the most frequent inquiries I get is "Where do I start?". There are so many BMW performance choices out there and some options are not going to give you the end result you desire. It is critical that you select wisely, buy excellent quality parts, and install them correctly.

For most late model BMWs, the best horsepower gain per dollar is through a performance software upgrade. There are a variety of suppliers out there who offer software downloads to increase horsepower and torque and also usually remove the top speed limiter and raise the redline. For BMWs manufactured after 1996 in the US this is very important. Until the software is upgraded, an intake or exhaust will not result in any performance gains.

After the software upgrade, then I would recommend a BMW air intake to get more air and cooler air into the motor. These are usually fairly easy to install.

Once these steps are done, then consider a performance exhaust. This will provide less back pressure, more horsepower and a meaner exhaust note. Brands like Active, Remus, and Borla are common BMW choices and can be found at most BMW parts retailers. Do some research to make sure you are buying from a supplier that is able to provide you the most accurate advice for your specific model of car. Buying the right part the first time, before you install it, will make sure yo get the hp gains you desire.

Each of these modifications is easily reversible and will increase the driving enjoyment of your car. Please make sure you follow the local and state laws where you reside for modifying your BMW.
