I love that car but I realized that I had in many ways grown out of love for it. However ended up with it is a lucky man. It was cherry/fast and IMHO the best looking Z I had ever seen. But that is because I made it look the way I liked. I too didn't like the HKS Hiper Exhaust but bang for the buc wins in my book every time.
Good luck,
