[QUOTE="whitedevil95, post: 15725399, member: 133221"] I was going to ask you if your catback was still stock. The stock mufflers are pretty restrictive. Back when these cars were being built they were under some new federal noise restrictions and Ford put some really quiet mufflers on them. I remember when these cars first came out people were reporting like 20-30hp gains from just a free flowing catback. [/QUOTE]
