Pretty impressed. Throttle response is noticeably better, engine feels like it’s running more smoothly, and I low key feel the slight HP gain. Not bad for the price. I think there is a slight sound difference as well, but it’s hard to notice over the short tails.

I remember on a dyno day, we had 2 Zs with the same cat back only and nothing else) same model year. The one with drop ins made 10 more wheel horsepower than the one with stock filters. Not the best test but it's something.
