I loved it. I had it for 7 years and I never had a problem with it. Nice throaty sound, but not too loud. It was still on the truck when I sold it, but it was getting towards the end of its life (it was only aluminized).
I did not see many others with a Gibson like fordtruckman said, but I considered it more exclusivity than a bad decision.
I have the sport truck dual on my 05 4.6 and if you like being noticed go for it but if your gona be pulling often they are noisy . I think I have one of the best sounding trucks and I live Ford country. this truck teases alot of others they all to drag. very easy to install 1.5 hour
I just got one about 2 weeks ago. I was at work, and heard a nice set of pipes, started talking to the guy and he had just installed a Flowmaster SIDO system. After talking to him for a little bit, he sold me the old system off of the truck (04 scab 4x4) for $60! Couldn't pass it up. He changed it because it wasn't loud enough. Needless to say, I was pumped. So after installing it, I was a little let down. In the cab I couldn't tell any difference in sound. Behind the truck at an idle it's a little throatier. When the wife did a drive-by at speed it sounded a lot better, but still not very much louder than stock, just had a real "burble". I still can't complain, for 60 bucks it was a steal. 3'' system catback. Here's a thread I started asking about it:

I've been trying to figure out how to make it a little louder, probably gonna just buy another muffler and install it eventually. It is a good quality, and a nice stainless tip polished. Hope this helps. By the way, when I say it isn't loud enough, I'm not looking for somthing really loud. I just want to be able to hear it when I nail it, esp. at wide open throttle. I'm not trying to make it annoying, just sound good.
I have the Gibson Swept Side setup. I chose it because you get all of the power of other catback setups without the deafening roar. It does make my truck throatier, but mostly at the exhaust. (Except when towing & when I get on it.) Neighbors and friends told me that my truck sounds mean, but if you want a mean sounding truck I wouldn't choose a Swept-Side Gibson.
I had a Gibson swept side stainless setup on my old Ranger and it held up good. On my F150 I have the Aluminized setup. I have had it on for 3 years now and it is holding up good.
Gibson is an excellent product. Their name just doesn't sound as "cool" as some of the others. I had a Gibson cat-back system on my '92 F-150 for over 14 years (until somebody destroyed my truck). It was an alluminized SISO. Easy to install in the driveway, and NEVER had any problems with my exhaust from then on. ...the factory pipe and muffler were full of holes in less than three years. The factory exhausts really are pretty good these days unless you plan on racing or just want more noise.

When I was stationed in South Carolina almost everybody was running a Flowmaster 40 series and it was loud. I was the only Gibson that I knew of. Mine was much throatier. It had a nice low howl that resonated around 1500rpm and definitely had some muscle when I got on it. You could definitely hear it in the cab since it was a cat-back SIDO that had a side exit in front of the wheel (put the muffler under the cab). Many people commented that they though I had an exhaust leak to which I said, "I'm flattered. Thank you for noticing!"
On nice days I would roll down the windows and turn off the radio so I could listen to the sweet exhaust note (yes I'm a little weird...I love the smell of diesel too)!
