I was just wondering wat a good size for a sports exhaust sytem would be

well i dont think you need anything bigger than 2 1/2 inch for an injected 6.

2.5" with a nice set of headers and a hi-flow cat, will be a good start to any falcon six, EA onwards.

Single 2.5" for I6 and 2.25/2.5 Twin System� for V8

Nice pick up Perana, i honestly saw I6 up the top.

/me goes off to get eyes tested.

Sorry to steal the thread but whats a good size exhaust for a older x-flow 6

Yeah 2.5" would be good for any 250ci, 2-2.25 for 200ci.

2.5" my car lost power with that large exhaust.... made more power with a 2.25"
