From the research done by other members you will get the highest hp and tq gains from the JBA catback system.
People like how the Banks sounds but you will loose low end power.
I just replaced the muffler with a Spintech and I love the sound. With install It cost me $110.
We had a dyno day some months back and discovered that most people with just the airbox mod and a highflow air filter put down higher tq but hp numbers were just slightly lower than those with an aftermarket intake.
I would say use the money on a level kit from PRG instead of an intake.
