Can someone point me in the right direction to find some reasonably priced hi-flow cats. I am working on a new exhaust setup for the f150 right now. I will be using Flow-tech headers and they have a 3inch outlet and theres no way in hell I would want to run a 3inch exhaust on it. Would lose too much back pressure. So I am looking for a 3 to 2.5 convert then i'll run an x pipe with manual cut outs and dual 2.5 bullets dumped. All help is appreciated.
Heres the headers:

And an x-pipe with cut outs already I was considering but don't know the quality of it

I am running the Pace Setter headers on my truck and I bought high flow 3"cats from magnaflow. They slip on the headers and I used band clamps so that they could be removed for service. The muffler shop then put a piece of 3" OD pipe in the outlet then flared the 2.5" to fit inside. I am running 2.5" into a magnaflow x-pipe into a DI/DO muffler.

So just get the 3" cats then reduce it from there.

exhaust after cats

 

That looks awesome Hows the sound??

 

Sounds like a beast. It literaly pures like a kitten at idle but then it roars like a Lion when you are WOT. It kinda reminds me of the NASCAR races when they drive by. Just need to do the wifes truck next.....

 

I won't say anything about the high capacity plunger.

 

I want it What would a set up like that set me back, if you dont mine me askin?

 

Random Technology

 

Ya ya I know... it was the only pic i had and i dont have photo shop to cut it out....lol

 

Damn, I wouldn't mind that setup myself.

 

When it was all said and done it was right around 1k. I think it was $200-250 labor to install the exhaust after the headers. I installed the headers myself, the whole thing was cheaper than a set of dyno techs thats for sure...lol

 

man i would love to do that< i just hear the headers are a major PIA to install..Do you have the 5.4?

 

Yes I have the 5.4 and now that I have done it I know the tricks on what to do. So when I do my wifes truck it will be a piece of cake.

Here is a link to the original install thread. https://www.f150online.com/forums/sh...d.php?t=239548. I have since found a couple of easyer ways to remove the bolts since I had to replace the exhaust gaskets in them. If I would of had a lift and a few extra tools I probably could of cut a couple hours off the install.

 

Awesome, thanks bro..I will save that link

 

I have the same set up as Huitt, heres a clip of the exhaust http://media.putfile.com/Pacesetter-...DIDO-Magnaflow

 

Well I have decided against highflow cats. I will be getting a set of Pacesetters, then converting them to 2.5 after the collector then going into an x pipe(need to decide on one) then dual 2.5 inch bullets dumped. Now help me find an X pipe!
