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 570 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.

Garbage quality
Style: 30 pcs
Absolutely no rigidity/stiffness. Basically just a piece of foam. Not even close to a good quality sound deadening product. Whole box of 30 pieces weighs less then 1 piece of what i usually use. If you want quality sound deadening, do not waste your time and money on this product

Great adhesive and easy to separate
Style: 30 pcs
​The first thing I noticed was the quality of the adhesive. It’s incredibly tacky, which is exactly what you want—once it’s pressed down, it isn't going anywhere.It was easy to trim with a standard pair of scissors. Definitely makes a huge difference in rattles and quality of music inside the cabin. highly recommend and great quality for the money. The back comes off with ease and super easy to cut and place.

It’s not bad read my review
Style: 30 pcs
It wasn’t too bad as a finisher on top of actual sound deadening. However, be sure you apply it where you want it as it does not come off. If you try to pull it off, it leaves a nasty residue and some of the foam sticks to said residue
