Installation summary

Advanced DIY skills are required to install this Milltek Sport non-resonated valved cat-back exhaust system, making it best suited for experienced mechanics working with a lift. Preparation involves ensuring the vehicle is safely raised and allowing the factory exhaust system to cool completely before handling to prevent burns, while also taking care to carefully disconnect and transfer any integrated O2 sensors and electronic valve wiring. During the three-hour installation, pay close attention to maintaining proper clearance around the factory heat shields and checking alignment before torquing the 3.00-inch stainless steel clamps to ensure optimal fitment and prevent rattles.
