newage 3" exhaust system
is it beneficial to fit a cat back 3" system rather than a 2.5" system. is the turbo spool up any different? the car is a 53 plate sti with only a stainless exhaust as mods.

Any reduction in back pressure on a turbo car is good, but whether you would see any major difference between a 2 1/2" to 3" is debatable considering you still have a cat in place.
Go for a sports cat or de-cat to see the best gains (as well as a 3" system).

Shaun.

I ran 325 BHP on a 2.5" system .......... I only moved over to a 3" system to get up to near the 400 barrier !!
I can't see any benefit in your case IMHO
