Default Exhaust system: 2.5" v 3"

Pro's and cons on changing from a 2.5 to a 3? Obvious signs are that it will flow better but is it really worth the cost & hassle (not too much hassle mind)

The car runs equal lengths from X-Force australia and a TD05FE and a FMIC as of next week, and currently a 2.5" full system...is it worth changing the exhaust?

On the subject, time for fantasy exhaust league

Ultimate flowing system equals???

D/P = ?

Centre = ?

Rear = ?

Richard, that UK of yours is getting serious....

There was an article in this/last issue of Jap tuning magazine where they ran true back to back RR runs on just this subject.
The 3'' with re map (ECUTEK i think) yeilded good gains.
I also they tried a 3.5'' for max attack, but the gains were not so pronounced, and the cost high.
