I wanna get some interior leds, what bulbs do I buy ? a link would be appreciarted

Also, I really wanna get some mufflers, I'm gonna be welding and fabbing them up myself . I love the look of the Greddys , how you can see them if you are standing far back on the side of the car and that polished back taking up the whole bumper spot designed for pipes . not sure whoch to buy though. What others look like that and where should I order those from ? knock offs ?? links or ideas appreciated !!

Thanks guys !
btw, car thread starting soon after these mods and my suspension, already got the wheels and sounds system etc..
