I hope you guys don't mind but I have somewhat of an unrelated question pertaining to exhaust. My buddy who owns a 2006 Ford F-150 with the slow 5.4L v8 is looking to buy some longtube headers from his truck by pacesetter. He's asked me if he should go with a true dual or get the y-pipe that comes with it. I remember when I had the pacesetter longtubes on my old 2001 Ram I went with the y-pipe because I liked the idea of having just one muffler. What do you guys think he should? Purchase the y-pipe with it and run a 3" single inlet/2.5" dual out muffler, or go true duals? Thanks guys!

 

hopefully he has a tuner. cuz those things need a new tune just to run a CAI.

 

A new tune? I remember him running his current dual exhaust with a volant cold air intake kit before he purchased his hypertech tuner and recalling no problems. Regardless, he does have a programmer now.

Any thoughts with what he should do? Is it a waste to run a true dual? And if he did run one, would it be wise to purchase a magnaflow x-pipe? Your thoughts would be very helpful to me so I can give him a definitive answer.

 

maybe a ford forum would be better...

 

Or at least the Off-Topic section.

Y-pipe is cheaper, easier for the computer to understand a single pipe/muffler setup. You start attempting real duals, and you'll need to rig up new O2 sensors and everything for the PCM to properly read the air/fuel ratio from both sides of the engine.

 

I just re-did my entire exhaust. Its not the cheap way to go though.
