I just got off the phone with a performance shop (all they work on is mustangs) and was told that you actually loose horsepower with the american thunder catback. He recommended the MAC Flowpath Catback.

He told me that a stang that he worked on had an american thunder catback. The car was a 95 5.0 auto. He said on takeoff you could chirp the tires. When he installed the mac catback, you could spin the tires all the way through first gear.

Do you actually loose this much horsepower with flows?
