I have a zircotec coated decat that will be coming off the car shortly. its NOT 3" has an extra lamba port hole for a wide band sensor but can be plugged. Keeps the heat away from the turbo. in total it cost me around £380 buying it and getting it coated. http://www.zircotec.com/page/--performance-white/41 Looking for around £225 delivered. Unless your going huge power this decat is fine on standard turbos and hybrid i have a 19t cold side hybrid mated to this Thanks Dan
