Its basically an emission legal test pipe, without the exhaust noise level increase! ;o)

Underhood temps are reduced considerably!

It doesnt make cool-down noises like the OEM cat!

Flows exhaust much better!

No CEL! ;o)<ul><li><a href="https://forums.audiworld.com/a4gen2/msgs/1071739.phtml">https://forums.audiworld.com/a4gen2/msgs/1071739.phtml</a</li></ul>
