Have an 04 V6. I do not know if I want to go true duals, but if I put a flowmaster one in and one out with a "T" coming out into a dual, I am told that this will give me more horsepower as opposed to the flowmaster one in and two out. Was told that the two out sounds good but makes the car loose horsepower. Has anyone tried any of these. THXXXXXXXXXXXXXXXXXXX

 

naw, just run 2 1/4 duals, and you'll be fine, dont get flows!
