Borla Header..improved gas milage?
Anyone know if the 4th Gen. Borla header benefits gas milage or does it decrease it? Also, anyone know of the actual power increase?
Anoyone dyno'd a 2.5 rs with cat-back and headers?

I did notice a slight power increase. As for gas mileage it remained the same from what I remember.

I noticed a power increase, MUCH better sound and couldnt tell ya about mileage (it went down but I think thats just because I was driving it harder)

Boxer4racing's site states that there is a 10% increase in mileage on a NA subie with Gen 4 Borlas and Stromung high flow cat.

I believe Cobb tuning stated the borla/randomtec combo at about +5 HP and +7 ft/lbs.
