OK, I'm a newbie... I'm looking around for motor and exhaust mods for my 2001 V6 Sedan. I see tons of info out there for 4 cyl and Coupes. Does anyone have a link to sources of parts for my car? And what is the difference of a coupe vs. sedan for exhaust, suspension kits, etc. If stuff fits on the V6 Coupe, wouldn't it fit the sedn? I know the body panels and light housings can be different but what about the rest?
