Make sure the Muffler shop has a mandrel bending machine or you will loose power from factory. When they bend pipe with a regular old bending machine the inside of the bend gets pushed in towards the flow area making the inside diameter smaller causing restrictions. The mandrel bending machine keeps the pipe the same diameter all the way through. This is what is used on the full exhausts that are for sale for our cars.
