A lot of shop use pre-bent tubing like this http://www.jegs.com/webapp/wcs/store...10263_-1_10245 as mandrel tube benders as expensive and then they just cut and weld all the curves together which is basically how the exhaust companies make theirs.

 

What i did on mine was ordered a magnaflow SI/DO (single in dual out) 3 inch in dual 2.5 inch out and had a shop bend the pipes from the muffler out. Got the muffler off ebay for 100 bucks shipped and had the pipes bent for 250. As for the resonator, cant miss it, its at the end of your exhaust by the tail pipe, looks kinda like a mini muffler.

 

One last question the tubing in front of my transmission pan got bent a little. Will a exhaust shop be able to replace that or should I go to dealer and get that tubing?

 

Ouch! I go to an exhaust shop if you want it repaired, the dealer will just wanna replace it.
