Hi everyone.
Just purchased AWE axle back for my ZL1.
Is it pretty easy to cut with an exhaust chain cutter vs a sawzall?
I had a heck of a time on my SS with a sawzall so picked up a chain cutter hoping that helps.

Also. Do you have to remove the NPP valves and plug them in and zip tie up to avoid check engine lights? I thought you just unplug the harness, tape it good and tuck and tie it up out of the way but read about people connecting the valves from the stock exhaust and zip tying it out of the way.

Txs for any insulation advice. Can’t wait to install the exhaust and hopefully enjoy a deeper and a little louder sound
