Do a lot of ppl mod their ats?

I recently bought a 2014 ats 2.0t awd, and i started looking for aftermarket parts for it.. handful of companies make stage kits, and you can get every bolt on pretty much. I also used a dealer loaner, while getting warranty work done, and the loaner was an ats. It felt way faster then mine and it had a zzp intake. Thinking some one got a stage kits, and it felt fast. Never really considered a cadillac for tuning and going fast, but I love mine.
