Genuine Mclaren Part.
In contrast to the UK 600LT exhaust the US spec version has no valves and is a straight pipe system which has no back box.
Key Differences vs. the UK Valved System:
No exhaust valves – Unadulterated sound through out not only just in certain driving modes or high rev range.
Lighter weight – No valve mechanism and no back box means weight reduction. You dropping in the range of 8kg.
No software changes needed – The car doesn’t need ECU updates or remapping.
Pure, unrestricted sound – Slightly louder and sharper than the UK-spec system.
If you install the US-spec exhaust on a UK car, it’s a simple swap.
No ECU updates, no remaps, no hassle. Just unplug the valve solenoid, tuck it away neatly inside the car, and you won’t have any warning lights or issues. It’s a completely plug-and-play upgrade.
