Installed my Flowmaster Catback System
I just finished my catback exhaust system. It sounds great. I paid 290.99 on ebay. Everything was intact and it was still sealed in the box. The hardest past was taking off the old system. I have to break the grinder and reciporcating saw. Man, it was a good investment. I noticed that there is no hesitation on the acceleration anymore.

Green, How do you like that single exhaust. I have the stock system on my 96, and I need something a little louder. Besides that, I don't think that stock 2 1/4 or 2 1/2 inch tailpipe lets that 351 breath too well. I love the sound of duals, but want to keep my low end torque. I very rarely run over 2000 rpm's.

Steve it's not too bad,it is getting louder! But if i want loud all i have to do is fire up the old Ford truck i have,it has duals with glass packs!! 
The Bronco has a 3in muffler and tail pipe,just wish i could have taken off one of those converters!!

Actually, I have a 302 and I bought the bolt-on Flowmaster that came as a kit. It wasn't too bad to put on, it only took about 30 mins. The hardest part was taking the old one off. It doesn't have a really loud rumble, but it does have that classic flowmaster sound. There really isn't any cab noise, until you romp on the pedal. It was a pretty good investment. I found some that retailed for around $400, but I found some cheaper on Ebay.

Some pics on the catback
Here are some pictures on the exhaust. The catback is a little dirty, I took out the Bronco yesterday and got it dirty.

Guys... I'm still sorta confused about the welding, so let me rephrase my question.
I meant to ask if welding is required to
a. remove the stock exhaust
b. install the new aftermarket "kit"
I was planning to get the Gibson exhaust. Worked mainly on JP imports before and most of them are bolt on + new gasket type.
Help is appreciated.

you shouldn't need to weld anything to replace the stock exhaust. Keep in mind that a cat-back system will not replace the intermediary pipe (y-pipe) which houses the cat(s). Unless you get a new intermediary pipe (h-pipe), you'll still have single exhaust, probably with dual outlet. Of course, there are very small performance gains from a cat-back and very big sound gains if you get the right kit 
.
If you ever do want dual-exhaust, you're better off waiting to invest in that since your bolt-on cat-back (designed for use with a y-pipe) won't work with the new h-pipe setup. If you want true dual exhaust, I recommend finding an exhaust shop who either has a mandrel pipe-bender or who stocks pre-bent sections. They can fabricate you a completely legal 2-cat high-flow dual exhaust Flowmaster / Bassani / Dynamax / Borla / Whatever system for around $500-$600. You pick the type of muffler you want, and the rest is custom. For real power gains, you'll need headers too... but I guess this is all a little more info than you asked for.
Anyway, you won't need to weld the bolt-on cat-back system. It just might be hard to get the old pipe out without cutting it, and you don't need a welding torch for that.

Yep, I had to break out the grinder (to cut the pipe clamps) and a reciporcating saw (to cut up the old pipe). It was more work taking out the old one and installing the new one.

I just had a single inlet/dual outlet 40 series flowmaster with 3.5 inch stainless tips installed on my truck yesterday and man does it sound good. Cost me $280 at a local shop and it looks awesome with the big polished stainless tips.
