AWE Tuning has tapped 22 years of experience in unlocking performance to create one of the finest exhaust systems available for this upper echelon automobile.
Please note:
Catalysts are confirmed to fit both 650S and 675LT models
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.
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 wasn’t 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.
The AWE McLaren 650S Performance Exhaust is designed to perfectly smooth the aggressively raw tone that results from mating the AWE Performance Catalysts to the stock exhaust system. The resulting acoustic character is nothing short of breathtaking, offering a note that is both hard-hitting and exotic.
The exhaust is constructed from mandrel bent 304 stainless steel at 3” diameter throughout and features a small balance opening between the banks to produce the a desirable and exotic tone. The AWE Performance Exhaust features logo tips evoking the factory geometry in a discrete satin black finish, or a less subtle bare stainless steel machined finish.
