5 Stars
V8-like sound...no rasp very minimal drone!
The quality of this product was superb as well as the customer service of stage3. Once installed it sounded as close to a V8 as the 3.7 will ever sound. I picked up 2 mpg and it seems to run noticeably better. Wouldn't hesitate to buy this product!
