Fabspeed McLaren 570S / 540C “600LT Style” Valvetronic Sport Catalytic Converter Exhaust System


SKU: FS.MCL.570S.SC918V Categories: , ,


Why We Choose HJS Catalytic Converters: 

HJS German imported catalytic converters are made from some of the highest grade material you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the “straight pipe sound” while still being able to provide enough emissions scrubbing to prevent a check engine light.

Unleash a new level of aggressive styling and sound with Fabspeed’s McLaren Valvetronic Sport Catalytic Converter Exhaust System complete with revolutionary 918-style top exit exhaust tips. Fabspeed’s valved design allows you to uncork the full roar of the 3.8L twin turbo McLaren engine, but still gives you the ability to return to a more moderate level for cruising through the neighborhood by simply closing the valves.
