so he replied 80k on the exhaust. what would be a good price to counter back at him he's asking 140.
IDK its older than the ones I've seen ~80?
Your choice on the install, you can install the entire thing (catback) if you want it raspy but you will have to replace the mid muffler in a few years, they rust out on the GTIs and A3s.
If you want it quiet you just install the rear section (axleback) like me . From the picture he already did you a favour and cut the rear section off. Besides the GTI valance, you can do a GTI axleback install for $15 in hardware from Parts Source.
