If you're like me, at this point you've listened to every exhaust video on YouTube. The price on this one was my only hesitation, but having it on and seeing how good the black tips look made it all worth it! Oh yeah, the sound...Amazing! I've had a 5.3 with Flowmaster 40 series, so I'm very familiar with drone. This exhaust has none. The 40 hp is just a bonus (joke). Power increase? Not sure, but it sure sounds faster. rebate=you'll need upc off the box.
