I am interested in hearing from those members that installed after market exhaust systems.

I have cold air, and custom exhaust on our 03 Altima, and at certain RPM's it tends to have a drone sound. I find myself running in a lower gear (autostick) or driving faster in order to tune the sound to my liking.

I recently had a timing sensor replaced which helped but the drone is still present at certain speeds.

I'm wondering if you have experienced this with mods to the crossfire exhaust...

HAPPY NEW YEAR!
