I wanted to post something positive after not liking the GM perf. exhaust, overrated and a pass imo.

The Brembo brakes on the other hand, BUY them if you like pedal feel or are coming from a German car. I feel everything they quote in the release - 42% larger, 16.1 rotors, 84 percent increase in brake pad area, 31 percent reduction in pedal force and 12 percent reduction in pedal. Imo, well worth the money.

For me, I felt the stock brake pedal was mushy, especially on hard braking - how hard do I need to push to get some feedback or get it to stop? They never gave me confidence.

When bedding the rotors/pads today, they actually overpowered the tires and locked them up a little which is the feeling I would prefer. The stock brakes could never overpower the tires which is sad because the tires are made for a mileage goal and road noise (imo), thus not the stickiest compound available. The downside to the brakes, now I want to show them off and look for a new tire/wheel combo. Very happy with this addition. Yes, they are expensive but it is something I felt the first time I pressed the brake pedal.

What was your main issue with the GM performance exhaust, was it sound? Did you got with the dual exit or the single?

The brakes look good. After spending what they want for them, I'd show them off as well. Post up some pics of them behind your current wheels.

Looks like the removed this option from the 23 order guide (for the Yukon- not sure about Tahoe/burb). Bummer bc our yet to be picked up order had them and now looks like will have to get after the fact.

There's another thread in this forum where people may have retrofitted the PPV brakes which are similar but the caliper is not exactly the same. I believe the PPV retrofit is less expensive and more neutral colored.

When I am ready for this upgrade over the stock setup, do we "have to" go via GM part numbers or can we buy direct thru Brembo? I would rather see "Brembo" vs "Performance".

Months before I bought my AT4, there was a set of 2021 GM Brembos on eBay for $1800 that I should have bought and sat on until now. Now that I'll have much bigger wheels, I'll be needing them. Although, I would prefer an 8-Piston brake over a 6.
