HKS Silent Hi-Power?
I was on newcelica.org and came across this interesting HKS exhaust. Its the "Silent Hi-Power" available for 2000+ Celicas. I suppose you could replicate this same setup on a tC if you combine the HKS Hi-Power and a TRD or Magnaflow axel-back.




i dont know if performance would be adversely affected. the hi-power is basically a padded/insulated pipe. its a straight-through design that doesnt restrict flow. it would just quiet the magnaflow or TRD exhaust.
btw, I wish toyota made this rear apron for the tC (from the TRD celica kit)

I had a HKS Hiper on one of my alltracs (current one has it but its not running yet). It was quiet at idle but made plenty of noise when the car was under boost (car has a full 3" system, turbo back). It was a little noisy on the highway but would not have been noticeable if it wasnt for its trashcan 4.5" tip.
