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

these were mounted to Stock manifolds in the front and Gibson cat back single exit stainless in the back. smooth install and high quality. my old cats were clogged. these work great, give much better throttle response and fit perfectly.
