Everything You Should Know About Long Tube Header Install [99-04 Mustang GT 2V 4.6]

This is for those folks who are thinking about installing long tube headers on their 1999-2004 Mustang GTs on a 2V 4.6 motor. This is not an easy job so having extra bodies to help out is recommended! Thanks for my dad and brother for helping and supporting the build!

For anyone wondering, I had a P0420 CEL for the high flow cats I’m running by BBK, so if you don’t have cats or have high flow cats then I’d HIGHLY SUGGEST buying Dorman Spark Plug defoulers from the auto parts store (18mm) for $10, you drill a hole big enough in it and it essentially tricks the ECU into thinking that the rear o2 sensors (after the cats) are working when in reality it’s just spaced out a tiny bit, that’s how I got rid of my light since nobody seems to tune for no cats anymore.

Also, anyone who says "BBK Long tubes suck" is retarded. BBK is good for the money, the gaskets suck but the headers are very good quality for the money.
