Sound barrier
Ok. I’m a new first time vette owner. Bought a new 2018 m-7 1Lt stingray 3 mo. Ago. Love the car, wanted more growel so I removed fuse #42, I see exhaust film on all four tips, but not really hearing a big difference? Is there something else I can do without spending $ on exhaust to improve the sound of this impressive power plant? I’m retired, not a lot of extra cash to blow, I know this has been talked about a lot but somehow I missed it. Is there a place in the dic I can make a change to increase the volume? Thanx in advance for the help, you guys are very good at giving good advice wish I knew half as much about these new vettes.

With fuse 42 out, the valves will never close and with an M7 in Sport or Track it will never go into 4 cylinder mode. At this point it is as good as it gets for free. More noise will cost some dollars. Probably a non catalyst X pipe would be most bang for the buck.

Are you sure you have NPP exhaust?
