Message	On 98% of members car's here I'd say they see little to no gain by going from 2.5" to 3". However when we start talking 600+ rwhp it is going to start making a difference ~10-15 hp. 750+ probably a considerable difference ~25-30 hp. Start getting near 1000 rwhp and the 2.5" maybe killing ~75+ hp.
