so im thinking about getting some shorty headers because i don't want too go threw the nightmare of long tubes on a 4.6 2wd. so other than getting rid of the restrictive manifolds what other pros are there? current setup stock manifolds gutted pre cats 94106 highflows x pipe glass packs 45d out back o yeah 4.6 175,000 miles 2wd screw 03 looking at these http://www.summitracing.com/parts/P...y=Year|2003|Make|FORD|Model|F-150&prefilter=1
to be honest, you arent going to see very much of a gain at all going to shorties vs. your stock manifolds.
yeah^ shorties make your exhaust louder but there won't be any performance gains or anything like that. if you want performance your better off with long tubes
haha long tubes would be a nightmare for me haha plus you gotta tune and what not i think id rather tackle shorty's and fix my leak while im at it plus you gain a lil torque
where did you get your info?? thats all crap. you dont need a tune. they dont give you anypower over stock. long tubes will make it sound a lot mean and more deep. run it to 2.5in collectors then do 2.5in duals out. the only nitemare ull have with em it putting on all of the nuts...but theyre not any harder than shorties.
this is what you need: OBX 99-03 Ford F-150 F150 Lightning 5.4L Stainless Steel Header Exhaust Manifold | eBay
