hey guys this is my first post as i am brand new to here. My truck is a 2004 f150 w/5.4 and i have a little exhaust leak that drives me crazy. Was looking for some insight to wich are the best headers too buy for 04-08 f150's? thanks rob

 

Depends on your price range. Longtubes are the best way to go for volume increase and performance increase, but its a very difficult task, and you will need a custom tune.

Your best bet is to get a pair of shorty headers and replace the gasket, or just replace the gaskets and re-install but use Grade 8 stainless header bolts

 

Either or, it just depends on what you are looking for.

 

already have mbrp catback but probly just a set of shortys because i want to keep my stock cats unless someone sells a setup to connect long tubes to catback set-up in stainless

 

They sure do!

 

Since your truck is 2004, it has 4 stock cats. If you buy a stainless Longtube header kit with cats ( $600 for the OBX LT headers, cats, and Y pipe, or $1400 for the Dynatech LT headers, all four needed O2 extensions, cats, Y pipe with proper dual 2.5" to 3" outlet Y pipe ) so you will be forced to run just two cats. But the header kits come with the cats so you will be fine.

And before someone corrects me about the OBX kits not having cats, but resonators, thats the $500 kit, for another $150 you can get the hi-flow cats.

Way to go on not informing him on what brand of headers and costs .

Just picking man

 

^ ha ha

sorry guy, OBX!!!

 

are the obx headers junk? Nice flanges ect? where is the best to buy them? thanks

 

I'm sure what is the best place to order them from, but they are a very nice set of headers!

 

obx is very nice. i would choose them as i cant justify saying pacesetter because you have to get universal cats, get them welded in and 02's extended. if you dont want that much work, either obx or dynatech makes less work but more expensive.

dont go shorties, waste of money. they improve sound and NO power change. long tubes or nothing imo!
