greddy cat back gain

im wondering what type of gain I may see on the dyno from a 2.5 greddy cat back. I put it on today and im really not sure if it feels any different. I dyno 195whp with a buget y pipe, ebay intake with a K&n filter and Emanange ultilimte with about 11 degrees advance timing from a dek motor with stock exhaust!

Personally... I'd say anywhere from 2 to 7 HP.

more like 2-5. the y-pipe frees up the most power. the gains from any catback are minimal after that.

I say 5HP max, since the y pipe is the main HP mod u can do that will give u a significant gain

Why not dyno and find out?
Are there any differences in data with respect to data taken before the cat-back?
