I built my own 3" on my Charger with an X pipe all the way to the rear bumper with Flowbastard mufflers. I have less then $300.00 into mine including the mufflers. As all the local exhaust shops told me. Throughout an 8-10 hour day they could do up to 15 cat back or exhaust repairs ob different cars at several hundred dollars each or a custom like my car would tie up a hoist all day so $600.00-1000.00 was the going rate. Sorry no pics. Here is the finished product out the rear thru the stock tips.
