A while back a member in these forums was giving away his 2019 ZL1 exhaust and I jumped on it. Mainly wanting the NPP look I wasn’t expecting much of a sound difference.

Then I realized that the ZL1 has larger pipes then even the SS, wasn’t until I left the shop that I realized how much, nothing like the Borla Atak but I think it’s nice. Cut off at the end of the resonator and pipes supplied by the shop to handle the change in diameter to the ZL1 exhaust.

I also had my AFM valves cut out as I was beginning to hear a ungodly sound which I believe was one of my valves going bad, wasn’t too sure about it as I heard the V4 mode sounds not great but I haven’t noticed it at all. Fortunately my AFM valves were not monitored for some reason

How much did it cost to have it fabbed up and installed?

The shop I went charged $100 to weld their own pipes to convert to the larger size

Sounds very reasonable for something like this
