i put the gibson dual out on my 07 sport 4L back a few months ago. I love it. sounds so nice, very nice low rumble during idle, and nice deep bark when you WOT. inside the cab, the best part, no annoying loud drone sound while crusing on the highway.

I have a "everything Ford enthusist" at work, and I drove by him one eveing while he was jogging, when he got back to camp he come to tell me that was the best sounding V6 4L ford he's ever heard. I'm not sure about that but hey, I'll take the compliment.

On another note, install is easy, Gibson includes everything (except your spring kit just behind the cat, they include bolts, but no springs. you may reuse your, but mine were shot), and I did my install in about 2 hours, on the ground in the parking lot at work, I cut my old exhust off, an then just fit everything together under the truck, loose, got it all where I wanted it, and started tightening from the front back.

Like \i said, 2 hours, laying on the ground, if you have access to a hoist, that will help.

Is there a difference between duel and single outs Besides appearance? Im leanin more toward the gibson. Speciaific part number 619713. I looked it up on youtube and its like exactly what i want. I good low sound but not to loud. I dont want to make it sound like a v8 with it being a ranger of course.

Appearance is about it. I have the dual extreme one, thats 2.5 into the muffler with (2) 1.75's out. Where as I believe the single is 2.5 in 2.25 out. So technically the duals one have a little more pipe volume, however they have double the amount of bends (2 pipes) so I bet they flow and perform nearly identically. Like i said I have the dual extreme, had it on my last ranger too, i love it. Bought a single gibson for a jeep as well, Gibson's fit and finish is really good, and the price is reasonable.

Awesome. Thanks guys. What are your opinions on cold air intakes? I know ty add horsepower but do they affect the sound? My 04 has 143,000 miles on it so is it worth me getting one? I only drive the truck on weekends and plan on holding on to the truck for as long as i can.

I suggest having an exhaust shop custom bend you a system. That way it's exactly what you want, tip is where you want, all pipes nice and tight to body/frame/hidden, and the cost tends to be a whole lot cheaper. What you see pictured below ran me $200 without muffler (I ran what I already had).

Dual tailpipes tend to be considerably deeper in tone. If you bump the tailpipe size up from 1.75 to 2.25", it will lower the tone/deepen the tone of the exhaust. In fact my latest updated dual-out setup, I bumped from 2.25" tailpipes after the muffler to 2.50". Noticed no adverse effects in economy or performance.

If you want deep, powerful on acceleration, and mellow at idle, Flowmaster 44 is the way to go, though it does get raspy at high is a v6. I had 6 mufflers on mine until I found one that was right for what I wanted. If you're wanting quieter, but still really good sounding and deep, Flowmaster Delta 50 would be what I suggest. The Magnaflow just was too quiet for me. The Dynomax was way way way quiet. The Gibson was closest to a mellow yet great tone, just didn't have the volume I wanted.

My setup is: axed stock flange, added 3-bolt flange, 2.5" pipe from flange to muffler, Flowmaster Super 44 3" in/dual 2.5" out, 2.25" tailpipes dumped at spare carrier.

I have the MBRP kit also, I like how it's quit at idle but at any rpm it's noticable. The only thing I don't like is the drone on longer trips/higher speeds. Mine dumps at the axle and is turned down to the road. I have thought about adding an extension so it points out the back.
Another thing I like and Shane has done it also is the exhaust is hidden, no huge pipes out the side. I was never a big fan of duals, our trucks don't seem big enough for it. Everyone who does duals on a ranger tries to get around the hitch or under which is too low IMO.

The MBRP kit is reasonable too. I paid $259 on amazon. On their site it's $300+, so I said screw that. I also liked that they are a Canadian company. It might not be that important to you being an American but it was nice supporting a small company in my county. It's also extremely simple to put on.

I have the Gibson duel extreme system on my 06 4.0 and when I first put it on I wasn't crazy about it. It was to high pitched. After it burnt in it got a lower tone to it but still a little high for my liking. So I went out and bought bigger tips. They come with 3 inch Gibson tips but I picked up 4 inch cherry bomb tips from summit. It definitely helped with the sound! It's a low drone and sounds awesome. It doesn't sound like a v8 just a bad *** v6. The only problem with the bigger tips was that they stuck out a little but but I just heater the pipes up and bent then in a couple inches and it looks killer.
