Which is a better bang for the buck: Magnaflow or MAC? Looking for HP #, increase or decrese, sound and general inputs, thx.

 

The MAC's seem to have a rusting problem the Magnaflows are good I bought the Bassani and like it but if I had known about the Magnaflows I would prob have bought them try Justin@JDM he will hook you up

 

I can't speak for the MAC Lightning stuff,but the stuff they make for the Mustangs is terrible.Bad fits,made out of saltwater dipped and treated pipe,and guarenteed to be replaced in two years(If it even makes it that long).I would get anything BUT MAC.
