Choosing The Right Performance Exhaust

Today, choosing performance exhaust can be confusing. A common misconception is that "bigger is better". Many enthusiasts, and manufacturers too, seem to feel that very large diameter pipes are the only way to go for muscle car performance, while we at BORLA® have found for street use, big pipes just take energy out of the exhaust, both by slowing down exhaust gas velocity and by cooling off the gases. While exhaust may leave the port at 1500 degrees or more, at the tailpipe it's down to 150 degrees -- a sign energy has been lost. Velocity and uninterrupted flow are the real performance-making factors.

Furthermore, it is the low frequency range that has energy (the sound you can feel inside the car); big pipes increase the low frequencies, making an uncomfortable roaring or droning sound. A BORLA® exhaust system, on the other hand, is designed for less restriction, keeping the velocity and frequency high so the main sound is behind the tailpipe.

Late model cars and trucks are computer controlled to such an extent that it may take a period of time (600-800 miles) before the computer reprograms to reflect the improved flow characteristics of your new BORLA® exhaust system.
