Holy hell (wow) I can't believe how loud the thing is with that combo... Going to get a resonator installed today so I don't get a ticket. Headers into stock was quieter then all hell.
the resinator helps alot, it also helped me when I bought a CAI, it seemed to make the exhaust tone deeper but quieter for some reason compared to the sri
i think it's all the magnaflow. mine is pretty loud too in cabin. but i must say when i was standing outside of my car while my gf drove it, it sound really nice.
