Almost new complete catback exhaust system. I had this on my 2005 6mt g35 sedan for about five thousand miles before installing an aftermarket exhaust system. My loss is your gain.

Dealer prices for new components:
Muffler: $457
Sub Muffler: $335
Front Exhaust Tube (y-pipe): $1253
Total after tax: $2233

so save over $1000 and buy mine instead!
