Easy bolt on Horsepower! My car sounds pretty mean now. Great additional to my Flowmaster Mufflers. It's also C.A.R.B certified!

My personal opinion on the product is as such. On receiving the package I was a little stunned at the minimal amount of product for the price. I installed it in less than 10 minutes and immediately heard the whistle when I revved it up in my driveway. I took a few test runs and couldn't notice a big difference in performance. My mpg went up from 18 city (driving moderate) to 21mpg so I was fairly impressed and I enjoy the whistle which is very noticeable.
