AWE has tapped over two decades of experience in unlocking performance to create one of the finest exhaust systems available for this upper echelon automobile.

AWE McLaren Performance Catalysts:

The AWE McLaren Performance Catalysts are aggressive, unbridled and unique.

Verified to fit 650S and 675LT Coupes and the Spiders, the AWE McLaren Performance Catalysts are thefirst in the world to feature a200 cell hi-flow catalyst solution.

About the 200 cell HJS HD Catalysts

The easy route would have been using the standard 300 cell HJS catalysts, due to their dimensions. However, there is no HD (High Durability) spec 300 cell HJS catalyst, and the close engine placement and power output that these catalysts are subject to in the 650S, meant one thing to us, the 300 cell HJS Catalyst simply wasnt an option. The 200 cell HJS HD catalyst, while significantly more complex to integrate, afforded not only the durability we desired, but the added benefit of significantly increased flow over a 300 cell count catalyst. In short, we chose to do what we do best. Unlock performance.

Unrivaled build quality

AWE prides it self on craftsmanship. The AWE McLaren Performance Catalyst is no exception. Precision engineering and fixture development permits the factory heat shields to be re-used. Further, our integration of proper articulating stainless steel fully lined flex joints provide proper torsional relief between the engine and the fixed muffler mounting points.

Besides factory correct fitment and long-term durability, all this engineering adds up to an impressive peak gain of +18hp and +32tq at the crank and a maximum gain of +44hp and +68tq at the crank, as measured on the AWE in-house Mustang chassis dyno.

Please note:

• The AWE Performance Catalysts are for racing use only.
• This is a special order product. Meaning, there are no cancellations of this part once ordered, since this is a boutique build that follows different processes and material needs than the balance of the AWE catalog.
