Outer Limits 4x4 Board

ey guys
just wonderin about an exhaust for a 2000 hilux diesel non turbo, I got a quote he said he would do extractors and back at 2 and 1/2 or 2 and 1\4. Same price was wonderin which will give me more power?
Also if anyone knows any other good exhaust joints in the eastern suburbs would be greatly appreciated.
sorry if i seem clueless just brought the lux a couple of weeks ago and am new to 4x4ing.
Cheers

2 1/4 is enough. (i would have gone 2" but thats me)

I have a turbo onthe the same motor with 2 1/2", this would definately be too big for that motor.

A set of good extractors do make a great difference with new exhaust on these motors.
