I have the stock exhaust and I am looking for something new but it is hard to find much information other then peoples opinion on sound.

I don't want my exhaust to attract any attention from the law, it needs to be California legal. I have CAI, Tune, TB, Upgraded Coils, so naturally I want to flow more exhaust. So what do people suggest?

I found a video of the Dynomax that was impressive and their kit is inexpensive (around $350 for cat back)

Did anybody else see any data or videos for CAI/Tune 3.7l ?

Was looking at dynomax when considering exhaust, If your not looking to attract attention then its a great place to start, a lot of people say its one of the quietest catbacks for us and sounds decent plus I believe its the cheapest catback available (or was when I was looking)

I went with pypes, more aggressive and unique sound cuz mid muffler but pretty loud so probably not what your looking for, it was 2nd cheapest at 400$

donno about CA legal tho

Yesterday I ordered the Ford Racing Touring muffers from AM for $657. 50 state legal. We will be taking the car to the MCA Nats in Asheville, NC this year and the Mustangs Across America next year. Two 8,000 mile trips. My wife will be coming with. She is not a fan of loud exhaust so I was in a corner.
