Who out there has headers on an 01+ and if you do did you run true dual exhaust with the OEMl cats? Or how did you run it? Whats works the best and what should I avoid?

 

I would stick with a single to dual or a single/single exhaust, our engine isnt quite buff enough to run a true dual without losing some much needed back pressure... perhaps some of thsoe that are running a supercharger among other mods.. a true dual would be a nice setup to put in.. you jsut need the room to do it as well, and thats really tough to do considering you need a cat on each run.. and we ont have much room down tehre to do it.. unless yoru runnign a decent lift on yoru truck :-)

 

i have jba headers(got pics of the install on a different computer, ill get around to emailing them to myself one day)
all the rest of the exhaust is stock
id stick with single in single out style cat back.

 

we have actually tested true duals on these and its really not worth it, a good set of headers with a singe in/out is really the best way

 

Is there a difference in the 4.0 in the Ranger and the 3.8 in the v6 Mustangs that makes the Mustang engine more agreeable with a true dual set-up? I know several v6 Mustang owners with true dual set-ups, and it has never made sense to me.

 

^they sound like crap too (IMO). My sister had an '02 V6 stang with true duals and it had a nasty sound (and not in a good way) when you got the RPMs up there..

 

That weed eater with a borla exhaust sound?

The gas tank is in the way too isnt it?

 

worse... flowmasters, so its raspy at the higher rpms.

 

From a TQ curve standpoint for a 4x4. True duals on a short stroke motor is not a smart move. Most 4x4 guys are interesting in low to mid rpm TQ. Not 5000+ rpms.

A better way might be to extrude hone (or hand port) your existing manifolds and get a set of high flow contertors with a 2.5" single mid pipe. After the muffler it won't matter much what you do.
