It will cost about $100 for two obx mufflers and then another $250-300 labor, and still need an x-pipe. So much cheaper just to shop for a used stainless steel one instead of cheap aluminum pipes from local muffler fab shops. Besides wasnt there that generic full catback stainless steel system on ebay for like $179 shipped or was it $279 shipped, well I know it was under $300 shipped because a local Z guy gave me the money to order it from ebay and then I installed one on a his tt last summer. In return for my labor I kept his stock tt exhaust system.
