I have noticed the gain in both horse power and mpg. The CAI and cat back works together to yield best result. Will come back for more stuff

I was looking for something to make my car pop a little more. I'm completely gutted and all components have been changed. I went from a 3.5 to 2.5 exiting hole diameter. It pops but not as much as I was hoping for. But overall sound quality is nice. Doesn't sound ricey. Good for what it is.
