Okay, now that I've driven my V-6 with the Flowmaster single exhaust a while, it feels like it has a little more "spunk," and the wife noticed it too....About how much of a horsepower increase would any of you guys in-the-know say it gained? Also, I take back what I said about the tip being too big and the drone: The tip looks just right now, after I've had it a while, and the sound is great too, not an annoying drone but "exhaust music to my ears!"
