Also posted this in the V6 forum but the general 05 Stang crowd might be interested as well. Now, for the inevitable knuckle-head who accuses me of "trying to make my 6 sound like a GT", nothing could be further from the truth. I love my V6 and don't understand those that try to make theirs something it aint. Besides, plenty of GT owners have installed Flowmasters in their cars. If, as some would suggest, I'm trying to make my 6 sound like a GT, then what would a GT owner with switched exhaust be trying to make his vehicle sound like?
Had a Flowmaster Series 40 Delta Flow installed yesterday in my V6 and what a difference...now THAT'S an American car sound! Definitely some increased interior noise but well worth it given the low rumble (but far from obnoxious) outside. It may have boosted the hp but I'm not certain; may just be my imagination and I'll give it a couple tanks of gas to see if mileage increases as some have suggested. Regardless, it's a very worthwile, relatively cheap mod. and one I'd recommend to any V6 (or GT) owner.
