I put long tubes on another vehicle I own, and you need to look at the headers, cat, x-pipe, and tune all at the same time. It's not plug and play.

 

Exactly! You have to start from the top and work your way down, changing necessary parts as you go. It will take sometime to get everything into working condition. Shorties just bolt in place of the factory manifolds and your pretty much stuck with however the truck runs after that. Long tubes require some patience and money. As well as the truck may need a custom tune to compensate for the wide open flow of the new full lenght headers, x-pipe, high flow cats, and free flow mufflers.The long tubes I purchased and picture in the begining of this thread are for a single cat and a SISO muffler, so there is no need for the x-pipe.

 

Hey Schertz I understand what you guys are saying and also understand I'm not going to get forced induction power from an exhaust. I just want to see what my best options are, based on other peoples experiences and testing. I know nothing that is going to make good power is going to just be bolt on and I'm ok with that. Just don't want to work into something for little gain, if someone else has already done so.

 

If you are to get LONG headers, do you HAVE to omit the cats?

Also, you guys are killing me. I make the cats for a living. BASF makes the cats for the F150 truck. Don't make my company fold!

 

haha I don't think I'm going to eliminate mine, I think I am going to use Magnaflow high flow cats instead just to be legal.

 

yeah you dont have to eliminate them, just takes some work to put some back on haha

 

Do they make CEL Eliminators for the F-150 like they do for the mustang. I have an 03 Cobra with A bassani x-pipe and I add the cats or take them off as it has two configurations but when I run w/o the cats I run the Mil's which is how I have it now. Also, I don't know if you can use a programmer to do it as well. Just throwing it out there.

 

I dont know about that, but i'm sure someplace somewhere has something like that. Orrrrrrrr you could get the tune, and pull the bulb for the CEL haha

 

Whats a CEL?

 

CEL is your Check Engine Light
