been saving up some cash to get new pipes on the stang due to some bend and dent in the pipes. Been doing so research and i got many different answers. Im looking for manifolds back with an H pipe and out the back. not to loud nothing to complex aluminum pipes. cheap stuff. and most likely flowmaster mufflers

Some quotes
Mighty mufflers $300
Pro Mufflers $600?!?!?!? (freakin ridiculous) <-- when i drove over there they had no cars.. haha wonder why?
Auto parts (just for the pipes and no install) $200

reason for the post is i am curious as if to just by some 2 1/2 pipes from homedepot and buy the mufflers online and if anyone can get me some pipe benders do it myself.. not that difficult.
Any imput?
Other places to try?
