DEVELOPMENT:  We based our McLaren sport exhaust downpipes around 3.5″ piping for the best possible sound and support for increased horsepower. If you plan on tuning the vehicle or running upgrade turbos our McLaren downpipes are designed to support anything you can throw at them. We made a conscious decision to retain the factory McLaren heat shields for their proven effectiveness and a clean, factory-like installation and finish. Incorporating HJS HD 200 cell catalytic converters – designed to withstand extreme abuse – you can hear your turbos clear as day with no check engine lights or noxious fumes. You’ll enjoy the cabin presence and beautiful engine note from the 3.8L power plant with no droning in the cabin, only an intoxicating mechanical chorus.

HJS HD 200 CELL CATALYSTS:  We use the highest quality catalytic converters available, known for their industryleading flow and durability. These McLaren catalytic converters are efficient enough to meet strict EURO 4 emission standards while still allowing for an increase in flow – all without a check engine light. The HD design uses premium triple foil winding for maximum strength. The brazing stripe is an extra feature in the interest of durability – it prevents the core from moving or experiencing any damage from sustained high horsepower abuse. We use a large and appropriatelysized catalyst to allow for maximum gains – no compromises at Soul!

CONSTRUCTION: Each set of McLaren exhaust downpipes is assembled out of thick wall .065″ T304L stainless steel and rigorously quality checked in-house. Smooth mandrel bends and thick flanges ensure product longevity. Each set of McLaren 650S Sport Downpipes is tested in a fixture to ensure perfect fitment.

LIFETIME WARRANTY:  Enjoy your McLaren 12C exhaust components with confidence on both the street and track as they are covered for life! The team at Soul Performance Parts will quickly work with you to resolve any issues that you may have. We cover our HJS catalytic converters with an unprecedented 3-year warranty while the McLaren downpipes themselves are backed by our Lifetime Warranty.

    SOUL installed their Sport Cat downpipes on my McLaren and I couldn’t be happier. I was able to come down, tour the facility, and inspect the parts. Top Notch. Install was great, communication was great through the whole process. Highly recommended.
