Mine are pacesetters....when/if these rott off I will look at stainless. At the time they were north of $800 for the stainlessworks.


Funny story about pacesetter(not really). Bought some replacement manifolds for the wife's car, these have the integrated catalyst in them. Front one on, one bolt WILL NOT go in. On that back side, the manifold will not go on period. Emailed pacesetter and they are aware the rear doesn't fit, and once ironed out, they offered to swap it out for me. Yes, I either want to leave the car on jack stands, or take it all apart again.

So, guessing pacesetter is just generally trash.

 

I have stainless pacesetter lobgtubes in mine and they are holding up really well. I did buy some BBK gaskets as well instead of using the gaskets that pacesetter included. I had a shop do mine (only job I wanted to pay somebody for) and after the experience, he said he would never do a 5.4 f150 again. He did mention how much a pain fitting the passenger side was and he accidentally broke the transfer dipstick in the process. I'm guessing it's just the lack of quality in design with pacesetter, but for the price and the function, I ain't complaining.
