Hey guys i have a 2001 f150 supercrew. im doing a lightining style magnaflow exhaust on it. but im making the exhasut with a magnaflow muffler and there tips and some adapters and stuff from pepboys. my question is, is what is the diameter of the mid pipe of the cat to the stock muffler.. i have searched but have yet to find anything.. any help is needed.. thanks guys

 

Its probably 2.5"

 

Just did my exhaust today, it was 2.5''.

 

Thanks guys.. i have to see if i can get an adapter made for a 2.5 to 3 inch or think of somethign else.. i dont feel liek orderign another muffler at work. thankss if anyone has any sugestions let me no

 

if its a 5.4L its a 2.5" pipe. Sounds good, get that in & enjoy the sound
