Headers and h-pipe or cams

Trying to figure out which one would be the better purchase first. And h-pipe and headers or new cams. What are your opinions? Already have the Super 44 American thunder series catback system. If headers and mid pipe which do you recomend?

Header mid pipe. Cams make no sense if your just gonna push all that extra air through stock exhaust. As for brands I don't really have a preference on headers and midpipe. I do recommend off road h-pipe though. The xpipe will make alil more power but IMO the xpipe sound like crap the hpipe sound way better

Off road H-pipe is the pipe without the cats am I right?

That's what I thought. Usually a little louder than catted. How hard are headers to install?

Headers are not the easiest install but not bad. Maybe a 6-7 hrs or so with help. Loosen the motor mounts and jack the motor up to get more clearance!

Don't long tune headers get ride of the cats? Make sure you get an h pipe that'll fit your headers

No not always. Most of the time they eliminate the cats but I've seen mid pipes for long tubes that still have cats

You really need to open your exhaust up before cams. Now stock manifolds and o/r mid pipe will do good. Then cams. Or full exhaust then cams. Like said headers are a pain but can be done with help.

Well cats aren't required in Wyoming so I'm not worried about passing any sort of emissions testing. So I will be going off road when I do this. Thanks guys

Cats are required federally and it is illegal to remove emissions components from a car that originally had them. With that said, in Wyoming you'll never have to worry about it and there are plenty of ppl myself included who have run around in emissions states with no cats at one point or another.

As far as headers, not needed on a 4.6L until you get into much bigger power numbers. The stock manifolds on a 4.6L are not restrictive like they are on an old 5.0L and, as I've said numerous times, there is a reason the Terminator guys don't usually upgrade their manifolds until the 600hp level. What you need is a better midpipe, gears, then work on suspension/chassis stiffening, traction and the driver mod. Plenty of stock motored bolt on 4.6L PI cars with 4.10s in the 12 second range.
