I did not do the install but have a borla header on my jeep with a cat back and superflow muffler. It sounds good, maybe a bit too loud with this setup. Wish I could give you more info but after no hits I thought I'd throw you a bone.

didnt do it on mine but ive done manifolds on other cars, tricky not hard just got to know what your doing. you need the right tool and knowledge. make sure you dont break any studs or bolts in the head... might need torches, pb blast, patience....take your time, everything is doable. and also keep doing research.
also borla are good quality exhaust system...wouldnt be scare to go with that. know plenty of people that put them on.. so far didnt hear anything bad..

Took me about 4 hours to take off weld and put back in it sucks make sure you have ratchet wrenches.

I have a borla and between that and a flowmaster muffler it made a noticeable improvement in performance. But the front drive shaft hits it so I am having a custom exhust guy cut/bend/do something to get me some room. Taking it in on wednesday.
