I have this four piece set in like new condition. 3000 miles on the TPs but less than 5 miles (not kidding) on the DPs. The DPs are heat treated 2.5" 5 bolt pipes. The TPs have an O2 sensor bung welded into the passenger side for a wideband. The sensor is not included. Together at Z1 these pipes are $500 without the heat treating or O2 bung. I'm asking $300. I would much prefer to sell them together but I'll take offers on either individually. Text or email anytime at all. Pics available.
