Submodel (2.0,V6, SS, ZL1) - V6 (previously owned 2016 RS)
Brand of Exhaust - stock non-NPP
Type (Axle or Cat Back) - n/a
Pros - reasonably aggressive for a stock exhaust, especially when it downshifted into the right RPM range on decel, but not too loud or attention getting (except for that one lady who caught up with me and shouted about it being too loud after I pulled away quickly in the lane next to her when the stoplight turned green)
Cons - just not a dual-exhaust V8 sound
Do you like it or not - I thought it sounded really good for what it was, but had considered upgrading to an MRT aftermarket system based on online videos. I ended up putting over 40K miles on the car and never changed out the factory exhaust - if I had really hated it, I would have upgraded.
Submodel (2.0,V6, SS, ZL1) - V6 (currently owned 2021 RS)
Brand of Exhaust - stock NPP
Type (Axle or Cat Back) - N/A
Pros - loud and aggressive, attention getting. Multiple personalities, although Sport is my default.
Cons - (1) no performance gains from this "performance" exhaust option, (2) same as above - as much as I like the LT trim, I'm not going to have my V8 dual exhaust note, (3) for my daily-driver use, sometimes it is good to be able to get on the throttle without being loud and attention getting (as I could with the non-NPP exhaust)... and even the Tour and Stealth modes don't help with how the NPP sounds (great, but loud) when you open things up. The non-NPP exhaust had a bit more of a "Q-ship" feel to it - not calling attention to how fast the car is. With the NPP, sometimes just moderately accelerating out of a corner downshifts into a lower gear and it sounds like I am really getting on it when I'm not. (4) Encourages tapping the throttle to activate the A10's performance shift mode when decelerating from about 40-50. Not great for mileage, but a very attention getting downshift exhaust note!
Do you like it or not - yes, except when it is attracting the wrong sort of attention
