CrisisMusick, CONGRATS!!
question #1: the lights.....you have already gotten the berst advice about that from trm0002 above ^.
question #2: the exhaust.....I too have a V6, and did a LOT of research and listened in person to a LOT of exhausts before I made up my mine....and without a doubt, the best sounding V6 exhaust is the MRT V2. and the best place to buy it from is here....lowest price...and free shipping!!
