I think these cars are responding very well with simple bolt-ons. Just like 4th gens, you can knock a second off your quarter mile without getting into the engine or using a power adder. The caveat is this is 2017 and the parts cost more. Not just for 6th gens either, I put full Kooks exhaust on my 4th gen z28 back in 2011 and I paid almost a grand less then what it costs today.
