Cat delete pipe for Stock-ish exhaust

[RMpowerstroke]

I'm looking for a cat delete pipe (preferably stainless) for a stock exhaust.

I picked up a factory Ford Racing cat-back exhaust this past weekend. It looks like it is 4" but I havent measured it. I havent put it on yet and am looking for a cat delete that would work with it/the stock system.

From all my searching it looks like AFE once had one that worked with the stock exhaust but is no longer making them and the MRBP ones dont fit anything but their exhaust.

I also found one through Expandit but it is aluminized (I have an email into them asking if they would make one out of stainless).

Other than that my searches have been pretty fruitless. Any one/Vendors know of one that I should look at?

Thanks in advance.

do you even see the pipe where the cat is? then just go with the aluminized one

I dont care about looks... after some miles its all going to look the same and its under the truck.

... but is there any issue with mixing and matching different types of metal exhaust components? Plus if its available I'd rather have a stainless one.

My local muffler shop sells them and WILL install them believe it or not. But for me it helps because I have my pickup registered for farm use.
You can purchase the pipe and install it yourself. Simple slip joint and clamp. Least mine was but now I'm running a straight back, no cat Magnaflow 4-inch all the way back

that doesnt directly bolt on to the down pipe, you gotta end up using different screws and bolts and theres potential for exhaust leaks

My MBRP stuff mounts right up with the OEM piping. I used the MBRP 3.5" DP mounted to a MBRP cat delete pipe. This all runs to the OEM tubing where I cut out the muffler. The MBRP cat delete pipe has a 3.5" exit it's just past that point where the MBRP cat back exhaust will expand to 4".

yeah i had to return my mbrp pipe cause it wouldnt fit the factory down pipe.
