Hey yall new to the 2015-2020 F150s. Currently in the process of getting a 2019 F150 5.0 single cab long bed 2wd truck. I’ve had some thoughts about getting 2M Fab catless long tubes (yes i’ve seen how people hate these headers). I had questions about what defoulers are, how come it shows only 3 O2 sensor bungs for the headers and Y-pipe when i’ve seen 4 O2 sensors on the stock system, and like the whole process of installing them. I come from the 80-86 Bullnose forum so this is all new to me.

 

You'd be the only here with them, if you get them. Are the manifolds cracked or warped on your truck, or do you just have to have headers?

I've seen people give positive reviews on JBA headers. Don't know if you looked at those.

 

Ohhh really Brad? I thought more people would. I’ve seen the price of others and this seems “good” for the price and I’ve also heard they’re off brand versions of Velocity Catless headers. I was just wondering if anyone had experience installing similarly designed LTH’s

 

I can’t think of anyone in this forum that has a set. Maybe a lurker will chime in though.

It seem that there is a whole lot less modifying, and more maintaining going on these days.

 

What a nightmare................

 

I have a set of Kooks 1-7/8 long tubes on my truck with a 4" Magnaflow exhaust. I would NOT want to put the set of headers that you posted on a truck unless it was cab off or unless the headers broke down to pieces. My headers came in 4 pieces: Right bank, Left bank, and 2 piece y-pipe. They were an experience to put in on the driveway and I've been turning wrenches 55 plus years. The headers are extremely high quality and fit very well but be prepared to move some things around to get the desired result. Space is at a premium and save your exhaust manifolds......

The defoulers are to move the 02 sensors further out of the exhaust stream so it won't throw a code constantly. You'll have to modify the defoulers for the sensors to fit but it works.
