Exhaust sizeing

[sc00by]

Hi everyone, i have a 2.8l 4cyl turbo diesel triton. im looking at getting a exhaust system to give it a little more go and bit better fuel efficiency. what size would be best, i have looked on the net and havnt found to much info. would a 3" be to big? i have been quoted 3" dump pipe and 2.5" pipeing the rest of the way through. just wanting to know what the general size is for a smallish motor.

Cheers
Trent

Can't really go to big if you have a turbo, but somwhere around the 2.5-3" should be good. Just make sure you get it mandrel bent, although it will be more $$$ its defonately worth it.
