I have a 2004 Prius that has been a wonderful vehicle. Unfortunately, when I brought it in for it's 30K mile service, the advisor pointed out that I have a dent and pinprick in the tail pipe assembly. He then proceeded to quote me a price of $1,229.80 for part # 17410-21500 - Pipe Assembly. My question is, does anyone know why this assembly is so expensive? The (seemingly) equivelent 'Front Pipe' on other models is only a fraction of the cost. Any input would be appreciated. Thanks.
