nice one secaboy. I would say there is no point in modding the exhaust of the TRD model, if you do the result could be just plane rice. I suggest you just leave it mate as Toyota already spent so much on R&D to squeeze all the performance and yet give balance to a FWD car. I would have bought the TRD model but around 12 - 15K more it ain't worth it. I would rather get a FPV Typhoon or a GTR.
