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 wanted to add more of a low tone but I didn't want to have drone when the MDS kicks in. Replaced my stock muffler with this 12588 one 3" in dual 2.5" out and I can't be more happy. NO drone at all. I left the resonators in place. Great muffler for the ones that don't want to set off alarms but likes a little rumble.
