First of all, since you own a 1990 SC, you will need to replace the tank with a 1992 or above to run TRUE DUAL.What is the best exhaust for a 1990 supercoupe?
I had my exhaust custom made from local shop , I got 2½ duals running from Cat's back with H pipe for 300USD! Very quiet with super turbo mufflers! Lost some low end, but will be installing a 10% pulley soon!!What kind of price am i looking at for a shop to bend straight dual exhaust?
