Just wondering if my stock exhaust would fit on my gf's '4 ZX5?
Planning on buying the catback system from mbrp in 2.5" trim when it becomes available. My stock system would be great for her car. if it would fit.

Also, what is the ST's exhaust diameter?

Thanks

It will be very close, but a Duratec exhaust is not exactly the same as a Zetec exhaust ... IIRC the stock diameter is the same for both
