Thanks everyone. There is no rattle when driving and they feel solid when stepping in. I just wanted to be sure the knock noise was normal and based on the responses it seems that is the case. I love them so far!

Hi Everyone, I had amp power steps installed last week on my AT4. They are a little loud when they retract, there is a knock i hear once i close my door and they close. Is that normal? Should they be pretty quiet? Thanks in advance.

Should I go with the Borla Touring or GM Performance on my 2020 6.2 AT4? What are your thoughts on each one?

Hi Everyone, I just picked up a 2020 AT4 and looking into getting the GM performance exhaust since I wants something pretty subtle. Where do you recommend I purchase? Are there places cheaper than the accessory store? Thanks!

Can someone tell me the part number for the GM performance exhaust for a 2020 AT4 6.2?
