These are ADM downpipes with simply OEM cat shells sleeved over and welded. All welds were done to the OD of the pipes, the ID of the pipe is untouched. The O2 bungs are in the stock locations so you do not need wire extenders. These bolt right in place of the factory catted midpipe.

A tune is not required, they make a lot of power as just a bolt on. The only negative if you want to call it a negative is you will get a CEL, but the car runs perfectly. If you have any technical questions Andy from ADM can answer them further. These function exactly as they would if purchaced new from ADM except they look OEM.
