I'm sold! Increased mileage with Magnaflow.

Two weeks ago when I made a trip up to New York the Nitro with the stock exhaust averaged around 20.6 to 21 mpg. This past weekend my wife got back home after being in Tennessee for a week and when she returned home it was averaging 23.6 mpg. That increase right there to me justifies the cost of the catback. Hopefully this week or early next week I will get it back to the dyno to see what the power increase actually is. Stay tuned, more to follow.........

That's truly impressive. Looking forward to a Flowmaster 70 install shortly. Should be similar results, I hope. I assume that the resonator had been removed as well, right?
