I found a guy that installs them for a good price and he uses 'AP' brand cat converters. He says those have been sucessful for him in holding off the dreaded P0420 code WITHOUT installing a J spacer.

Pros: successful in holding off P0420

Braking:
Noise:

Love me some AP brakes on Exiges and Evoras. I once got stuck in stop and go traffic in an Evora after it spent all day lapping Laguna. No squealing, uneven pad deposits, cracks in the cross drilling...nothing. They're basically fade free too, which is super impressive.

Pros: fade free, no squealing

Vibration:

I just changed out a set of AP rotors that had more significant cracks than that on the outside of the rotor and only caught them because I was changing pads, I wasn't getting vibration under braking.

Pros: no vibration under braking

Cons: significant cracks on rotor
