I am new to this Forum. I have had a 2003 5.4 Expy for about 5 years now. I have had a small exhaust leak at the manifold for the past 6 months, but it recently became alot louder on the passenger side. I have already removed the passenger manifold and it looks like the gasket was bad. I ordered a set of headers from summit that say they will fit my vehicle. I am still waiting to get them in the mail, but I cannot find any information on anyone installing 2nd gen shorty headers. I am affraid they are not going to fit. There isn't alot of room in there. Has anyone on here installed shorty headers on a 2nd gen?
