Porsche 996 997 Quad exhaust tips

My 1998 Porsche 996 had been fitted with a C4S rear bumper at some point in its life. I wanted to get it back to standard so also needed to replace the exhaust muffler system to enable the standard bumper to fit as the exhaust exit locations are different in the different bumpers.

When removed I found that the exhaust tips fitted to the car are shown as 997 parts so would have been from a later car. The part number was 997.111.352.04 and showing a date of 7/4/2008
