2.5" vs 3" Catback

[Thrust]

Here is the deal. I have a 2.5" flowmaster cb with a o/r prochamber. I love the way that this combo sounds, but I think that my cb might be holding me back. My car currently makes 601 rwhp with this set up, but I am wondering if a 3" cb will make a worth while difference. I am leaning toward a 3" mac cb. Does anyone have any dyno #'s or experience with going up to a 3"cb?

I have a 3'' and I just dont like the sound.. To bad you wanst closer, I'd trade you for your 2.5'' Could use the extra boost in my mid range.

Seen many on here with 600+rwhp on a 2.5 cat back.

Bigger is not always better.
