Icon3 3.0 exaust and header questions

I've searched and read numerous different opinions so I figured I'd just start a new thread and try to find my answers.

#1 Can u run True Dual exaust? I've heard that u can't b/c Rangers don't have enough back pressure.


#2 I want to get some headers in the near future but was wonderin if they are worth it and how much do they help? And do they help your truck sound better, and how much better?

Thanks for the input, I appreciate the feedback!

I have heard headers do as much as tuners.. and can really work great with header back exhausts and intakes. they work well together.

idk about 3.0 dual.

Oh yeah. Nothing will void your warranty unless it's proven to have caused the failure. Just in case you have a warranty and someone decides to ruin another thread.

As far as I know, you can run true dual exhaust with the 3.0L, but no one makes a kit for it. You would probably have to get it custom made. I had mine quoted a few years ago and it was $2,000....I didn't do it.

As far as the headers go, they add low end power and work great when stacked up with cat-back systems and a tuner like the X-Cal II. Of course all I have on my truck is an X-Cal II and a K&N drop-in filter.

Run this:

HEADERS into a header back system with mandrel bends - to magnaflow high flows - to a dual in and run a single out. 2.5 in and 3.0 out.. that will show some nice gains.

yeah its not a true duall.. that requires new pipe from the headers. two high flow cats and two mufflers... a true dual is about 800 - 1000 i would guess.

Oh ya im not saying it was for true dual. But when we did them on a f-150 it was 538 but that was new cats and no mufflers. I just couldnt imagine it costing that much more for a ranger.

I don't think I would run true duals in any vehicle.

like others have said you can run true duals, I would keep the piping kinda low to either 2.5 -2.75, Ive heard that there is a lack of low end. You would have to get one custom made, if your cats are still in good condition reuse them if possible they are just as good as high flow cats, our engines are not a 351w or cleveland that makes a lot of power, no need to pay out the butt hole for a cat thats about the same as the one that comes stock on the truck. A buddy of mine got true duals on his 07 lariat F-150 looks and sounds great full 3' from headers to the tips costed him $600.

as for the headers they are great they will deepen the sound of your exhaust and when other mods are done to the engine like a supercharger, porting, exhaust, intake, cam... etc etc. Im actually looking into some headers for the future but they are just to damn expensive JBA's are the best from what I hear, gibsons are alright but for the money its best to fork out more to get the JBA's.

Good luck and have fun disturbing the peace

I have the JBAs and I like them, I gained 2 MPGs and picked up some good power and torque. I need to do exhaust too, but I like it quiet and I don't have the money right now anyway. Next may be a tuner or a CAI, but gears and a posi are gonna be a must too. So much to do, so little time and money...

True dual would be a PITA on the 3.0 if it is flex fuel.

It would be possible though. I'd do 2" on such a small motor, though. It would take quite a bit of fab work but anything is possible with the right ammount of time and money.

Yeah really no point in having true dual exhaust set up on a small motor like the 3.0.... Or a large v6 like the 4.0 either.. True duals on a 5.0 f 150 or mustang with original 40 series mufflers sounds AMAZING.. Just stick to a nice cat back system with some after market headers.. Remember, you shouldnt just buy headers or cats just for "sound" You want performance...

It's all smoke and mirrors. Looks cool and sounds good. As for performance you need to actually tune the ecu maps if you want to make a difference you are going to notice. Stick a wideband into that exhaust, do some 3rd gear pulls and log your AFR's vs RPM. Advance the timing, and lean it out some until you get a bit of knock, and then back out of it. 11.5:1 is usually really good. This will give you more power than any bolt on exhaust will.

our trucks dont make enough power to where "high flow" cats will generate any performance gains. The ones that come stock are already "high flow" as they can support boosted and N20 applications... which generally are around the 200 hp/tq numbers. There is a lot of hype about gaining more low end but Ive heard many complain and gripe about them but when on a dyno theres no gain sometimes depending on the mods the stock cats did better but not by much. Id save your money from buy those "high flow" cats and put that towards a turbo or supercharger.. or whatever you want. Headers are definately worth the money if you have extensive mods done to the engine, like actually gone into the block... the headers will give a deeper exhaust note but for $400 they are pricey.

You make more power when you run a X pipe because of exhaust scavenging. I would only run true duals in a fully built race motor or a twin turbo motor.

well from the factory, it has an h pipe, but it is still considered true duals.

Why would you want to run true duals with a 3.0l?
