I have the 94-98 generation Mustang. I lost all the low end power gained by the dyno tune by installing 2.5" mid pipes after the cats. By installing 2.25" pipe which is the size pipe exiting the cats, I gained it all back and then some. When you get to the mufflers everyone or anyone puts on 2.5" mufflers with any size increase tips.
Hope that makes sense & helps.
