Heasers on a 4.6??
Headers on a 4.6??
I was thinking about putting headers on my truck. It has a 4.6 and only mods are a magnaflow muffler SI/DO dumped right before the back axle.
I was thinking of cutting out 2 of the cats also or is there an aftermarket x-pipe or h-pipe w/ cats for the f-150's that make it a true dual exhaust??
was gonna put on spintech mufflers as well
