2017 Exhaust question

so what vendors offer an exhaust that uses the NPP, but in 2017 they removed the valves before the mufflers, only have the rear valves near the tips. 2017 Grand Sport 7 spd car.

Borla is one of the few that make the cat back exhaust that has the npp. Not cheap at all but if you go for it get the atka set up for the car. It is only a hair louder than the stock set up.

Two different types of valves. The valves you're talking about are the active fuel management valves that are not on the GS. Z06 exhaust should work since the Z06's do not have AFM actuators. Corsa does not make exhaust that use NPP. So look into Borla's Z06 exhaust.
