Thermal Research & Development exhaust... compared it with my friend Adam's 02 GTS w/ TRD
exhaust and mine is louder and deeper, and i got it for FREE.
also traded my Wings West wing to Adam for his TRD
. He's parting out his kit and agreed to just trade (both of our cars are black so it was easy).
i'm in the group by for the carbon fiber C1 raised scoop so i'll have that before too long, and after that will be a drop (Tein S.Tech springs).
