Why do the highest modified Supras and RX7's only have single exhaust? Does a quasi-dual exhaust give you anything except aesthetics since the gases have slowed by that point? Do duals really give you anything on a 2.5L motor that a good single exhaust system can't? I have duals on my car, but I have a hard time believing that a good single setup couldn't be as good. The only thing is aesthetics on the SVT's b/c there are two openings in the valence panel. Think about that... :rolleyes:
