Hmmm - before I plunked down $5k on headers and exhaust + labor I would ask to see a dyno.
When most people say they want HP - they really are looking for more torque and / or better overall acceleration. The 3.2 headers / exhaust are pretty good and I would just want to make sure
1) you are not loosing horsepower or torque
2) you are actually gaining horsepower or torque
3) the power is over a broad RPM range
I would hate to see someone drop 5 large and loose power from 1,000 - 6,000 RPMs but then pick up power from 6,000 to 8,000 RPMs but actually have the same or slower times to 60 or in the 1/4 mile.
Please hold your flames as obviously some of these solutions are good and I don't know exactly what you are contemplating.
