Hey, my friend just picked up an 03 lighting. Low miles in real nice shape, and were looking for some mods to pick up some more power. Nothing too crazy, just bolt on stuff and for now he doesn't really want to do an exhaust as it has a nice rumble already. What works on these trucks and what doesn't?? Also is there anything to watch out for?

Thanks
