i was thinking of making a custom made exhaust for my 95 gt,but i dont know hot thinck should i make it ( 2.5 or 2.25 or 2 inches???? can any one tell me????
2.25 or 2.5

Depends also on the inlet of your muffler

Magnaflow RS have 2.25 inlets (many)

apexi N1 has 2.5

2.5 - 3.0 inches if ur going turbo. But 2.5 is still ok for a GT personally I would stick with 2.25
I did my exhaust in 2.25.. sounds/runs great
