I also have an HKS Sport Turbo Exhaust.
It is somewhat rare as I have never seen it on any other cars and surprised to see it twice here on MR2OC.
It is a huge upgrade to the stock exhaust and works with the stock OEM B-Pipe so it is very much street legal looking. Should have no issues passing smog. I passed smog with this exhaust 3 times.
Is generally in great shape with the exception of one small dent on left side. Not very noticeable.
Comes with OEM-Bipe and OEM Cat. Those alone are worth a lot.
