I have the following up for sale: (unfortunately i have to let go of my car so i need to clean out the garage as well)   Porsche 996 Carrera bypass pipes to suit Carrera 1998-2005 inc GT3, had them one for ten minutes. About 10meters max. Pipe size is 2.25", tip size is 4.5" X 3.5". Really good condition. $200   Also have a pair of NHP X51 Styled headers they suit all 996 Carreras (3.4L & 3.6L). Long story short only had one of them on due to snapping too many bolts. Only had it on for 1
