I know that running longtube headers on a 2003 F150 with a 4.6 V8 is possible with a little bit of modification. I'm wondering who on this board runs them and how much fabrication was needed. I know this subject has probably been mentioned a 1000 times in the past. I have also heard the Mustang longtube headers will most likely work on my truck also? Any advise is greatly appreciated.

Thanks,

not sure why this is in the SC/TC section but maybe this will help. These are the Dynatech headers. http://www.ford-trucks.com/article/i...tallation.html

 

faster150 has a set of kooks long tubes on his 4.6

 

got my pace setters from summit i think they fit the 5.4 and 4.6 for some weird reason, im sure there out there
