Need help buying exhaust!!!!

Wouldn't it be better to just bring it into a shop that will custom bend up all the pipes for you and hang em up nice under the car? I had a Summit exhaust on my Duster and it was OK when I first installed it but after a few years i realized i got what I paid for when it started to slowly get old and decrepit. I just recently took my Duster into a shop that bends up the pipes on site and they tore off my old exhaust and ran all new custom bent pipe from the headers back and put on 2 new Flowmasters and chrome tips. Car sounds GREAT and the final bill was not too bad $475.00 They also used all welded hangers and the exhaust looks awesome tucked up under the car nice and pretty!!! They used 2.5" pipe and I have noticed a considerable increase in power with the new system. I also have recently changed out my transmission to a TCI Streetfighter 904 with a 2800 stall converter. Man what a difference when I punch it on the highway. She takes off like a rocket!!!
