It is letting my truck breath better, which is helping it sound like a truck. Sounds great and is running better.

Great product I noticed the performance right away. I love the noise it makes at wide open throttle, reminds me of an old muscle car with a big 4 barrel carb. My truck is getting a little better mileage too.
