In reference to Cowboy's question about the stock exhaust. I also liked the quiet exhaust and only wanted a just a stock size cat delete pipe that would replace the section from the down pipe to the muffler. I never did find one the was the stock 3.5" only 4". I searched ever thread I could find and general look up on search engines but never found one. I went ahead and ordered the Magnaflow turbo back. Before I ordered it I called Magnaflow and asked for the specific part number of a kit that included the down pipe that would make it a true turbo back kit. When I ordered it and it arrived it had everything but the down pipe. Anyone else have this experience with Magnaflo and does anyone know a company that makes or sells a 3.5" cat delete pipe?
