My dad just bought a 99 Lexus GS400. I want to make it faster without him knowing it, like ecu, intake, pulleys, etc.... The only thing I cant change is the exhaust. I would like some links or pics, or any info for that matter on how to make this thing faster, and handle better. I could change the exhaut if it is a quiet system.
