This installation requires cutting
Borla explicitly states that the original exhaust must be cut. Decide how the removed equipment will be stored and whether future restoration matters before authorizing work. Do not promise a wholly reversible, untouched-original installation.

Identify the correct system
The listing describes a 3-inch S-Type system with functioning NPP valves, merge X-pipe and dual carbon-fiber tips on each muffler. It is specifically configured for ZL1 and is not recommended for convertibles.

Set the installation boundary
Obtain the matched installation PDF and have the installer identify its cut location on the actual vehicle before making a cut. This reference deliberately supplies no inferred distance or cut line. Record the exact part number on the work order and keep the removed original sections. Alignment, fastening and valve operations remain governed by the complete manufacturer instructions.
