AWE Tuning McLaren 3.8L Performance Catalysts

AWE Tuning McLaren 3.8L Performance Catalysts:

The AWE Tuning McLaren Performance Catalysts are aggressive, unbridled and unique, and are the first in the world to tout a 200 cell high 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 shorter overall length. 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 Mclaren 3.8L V8 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 Tuning prides itself on craftsmanship. The AWE Tuning 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 allow for torque flex without stress.

Along with factory-correct fitment and long term durability, the AWE Tuning McLaren Performance Catalysts provide peak gains of 16 hp and 10 ft-lbs of torque at the crank and a maximum gain of 17 hp and 15 ft-lbs of torque at the crank, as measured on the AWE Tuning in-house Mustang chassis dyno.

Please note, the AWE Tuning McLaren Performance Catalysts are for racing use only.
