IIRC when L27'* were still fighting to be on the 1/4 mile list, 2 or the 3 cars were 93'* with 2.5" pipe, and the other was a 94 with exhaust work.
That being said, I certainly wouldn't go bigger. But if anyone wants to upgrade pipe, i'd find an SSEi exhaust setup @ a junkyard and install that. I would love to actually have the chance to compare two 93 cars, with the 3.06, and both exhausts to see what differences may be present.
