I have a 1996 Mustang Gt with a few mods. For exhaust I have a 2 1/2 in. X-pipe, 2 1/2 in. catback, 3 1/2 SS tips. If I were to buy Mac 1 5/8 in. Long tube headers how much louder would my car be? Also how much more power might it give me? My car is pretty loud now but I love loud cars so would this make it too loud or would it still rumble and sound nice? I also have a fenderwall intake and plugs and wires if that matters at all for the HP question at all
