well i kinna can...i pull way harder...my buddy has a gsr and he has i/h/e and before i jus had full catback and cold air and now with this i jus leave him on a 60 roll...but the speed limit is 70 so we dont race...jus up to the speed limit lmfao
so i guess it did help and for 300 with defouler shipped wasnt bad
