Porsche facelifted the Cayenne in mid-2014, creating the 958.2 for the 2015 to 2018 model years, with revised headlights, a new front bumper and a restyled tailgate. Because the 2014 model year straddles the changeover, confirm your car is a pre-facelift 958.1 before ordering. Milltek does not offer a facelift 958.2 version of this part.\u003c\/p\u003e\n\u003cp\u003eDesigned and manufactured in the UK with 40+ years of performance exhaust heritage.
