1. My V6 sounds like a 4 cylinder without a muffler at low speeds. At Cruising speeds the truck sounds fine but when i hit the gas it sounds like a 4 cylinder street racing car.2. Performance is good and seems yo help gas mileage.3. Installation took longer than 2 hours since i was working from the ground. The instructions say to cut tailpipe at muffler as 1st step. I suggest you follow this instruction. I tried to remove it as 1 piece and its impossible.4. Can somebody please help me fix the sound issue? The youtube videos sound way better than the actually product.
