anyone tried just putting straight 3'' pipe after the cat,exiting in the stock location??

 

I've seen dual pipe on a 4.6 truck after the converters with no mufflers. It wasn't real loud, just a nice noticable tone. The converters usually muffle the sound pretty good. This should give you a little more mid-range and top end power by reducing back pressure.

 

I have a 1994 F-250 with the 460. when I bought the truck it had a 3" strait pipe on it. It wasn't loud even pulling a trailer. It had a nice rumble to it. The converters on these trucks are so big and long that they muffle the sound enough. I would go for it.

 

Andy if your still out there. Thanks for the info. Another question. When I install the stud rocker heads can I still use my ols push rods tha were on my old pestal heads? (9.5 to 1 compression is just what I,m looking for. I,ll be pulling a race car on a trailer and with a camper type cam it should work great.I,ve got to wild a cam in it now for the street or for pulling. Sam in memphis

 

alright sounds good, your right the cat is huge. what do you think?? single 3" or dual 2.5". cost maybe big in the two.
