paintless dent repair

Anyone out there ever used paintless dent repair(dent wizard)? I've got some door dings that drive me nuts every time I wash my car or look down the side.I can't afford a paint job right now and I've got other things I'd like to do first.Paint is original and still looks decent ,except I have to buff it twice ayear because whiteish bloches appearn if it sits in the sun for long periods.Luckily it's in the garage most of the time.I was told the paint was losing it"s pigment.
 
I've used them twice. Most recently, a guy took a ding out of the left front fender and one out of the left quarter panel of our Cobra. You can't tell they were ever there. If he knows what he's doing, the process works amazingly well.
 
The dent wizards usually do a really goof job on a small dent they will being it out about 95%, for the savings tho i would say its worth it. You really wont see it unless you know what your looking for. If there is a crease or anything like that they wont attempt to work on it cause it means the metal has been streched and filler is the only answer.
 
off road X pipe vs. flowmaster catback!

which one is worth more power on a bolt on + 100 shot 5.0, i have to choose one or the other right now and not sure which one to keep, i will either run the stock H pipe with the flowmaster catback or my offroad X pipe with the stock mufflers and catback.

which one do you guys think is best?
