AWE Performance Catalysts for McLaren 3.8TT - 12C / 570 / 600LT / 650 / 675LT

AWE has merged over two decades in supercar performance products with rigorous study of the peerless engineering behind the McLaren MP4-12C to create one of the finest exhaust systems available, for one of the finest vehicles available.The AWE MP4-12C Performance Catalysts are aggressive, unbridled and unique. Verified to fit both the 12C Coupe and the 12C Spider, the AWE MP4-12C Performance Catalysts are the first in the world to feature a 200 cell hi-flow catalyst solution. Due to its dimensions, standard 300 cell HJS catalysts would have been far easier to fit into the McLaren. However, there was 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 MP4-12C, in our analysis, mandated better. The 200 cell HJS HD catalyst, while significantly more complex to integrate, afforded not only the durability we desired, but the added benefit of significant increased flow over a 300 cell count. In summary, we chose to not settle, because the MP4-12C deserves it.AWE precision engineering and fixture development permits the factory heat shields to re-attach completely intact, with no deformation or subpar installation results. 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 +46hp and +61tq, as measured on the AWE in-house Mustang chassis dyno.Please note, the AWE Performance Catalysts are for racing use only.
