Shorty or LT headers?

I have a 2004 3.9L v6 and I was wondering which choice would be better and if the long tube headers are a lot harder to fit? Plus would the both work since I have a y pipe flow master exhaust and not a dual exhaust?

The long tube headers are a bit cheaper on AM.

Longtubes show better performance. Shorties slim to no performance. So definitely get LT's as for the y pipe situation I'm not real sure idk how those are under there but since your headers will be LT's they are longer than stock manifolds so you'll need a new midpipe.

I got BBK shorty headers and I didn't notice much of a performance gain but my exhaust was defiantly deeper!

This question was answered at least 4 times today. Lol
Longtubes are better performance wise but really arent worth the money or hassle unless you're making a drag car. Shorties are pretty much just for looks and are only needed to replace broken stocks.
Id spend the money on mods that are more worth having.

If emissions will let you go with long tubes. It'll sound awesome since you'll probably have to take your cats off, as long as you have a good set of mufflers.

I've got shorties on my 2008 4.0 and they picked up some mid range power and noticeably deepened the exhaust note

If you want cheap shorty headers, the 94-98 v6's have factory headers that will fit on the 99-04's.
