What's the difference
This was an era where Toyota made "L-tuned" parts and were commonly available from dealerships. It was kind of like today's "F-Sport" line. They made a great exhaust, shocks, nice wheels, and other things (side-skirts?) that other people may have more knowledge on. Some GS430s got this "L-tuned" package but they are so rare. I've never seen one in person but that's probably the only way you could tell if it was genuine, is to see a genuine one in person, and compare it to one that might have been pieced together with seperate "L-tuned" parts. I do know however, there were very few 2005 GS430s built. L-tuned exhaust and wheels are almost impossible to find second hand nowadays.
