Deep pleasent sound, not noticable from inside car at cruising speeds. Considered Stasis, but at nearly twice the price and they use Borla muffler, I couldn't justify it. too soon to comment about mileage or power gains, I will say it revs easier and faster. I has been on the car for less than a week.
