I have a secondary cat delete already, but like most... it wasn't enough. My corsa xtreme axleback came in today and I was just curious. When I remove my NPP mufflers will I be able to reinstall them if I wish? I feel like one day I may want to retain the dual-mode functionality, which isn't possible with the Xtremes. To do so would it have to be removed in a certain way? if so, how?

You should be fine, I'm expecting mine to be in Monday and in the intrusions it says just unplug the harness from the valves and tuck it on the body and zip tie. Be sure to tape the exposed connecter with electrical tape.

You will be cutting your muffler at 2 points but you can have it welded back if you ever want to put your oe exhaust back on.

The corsa extremes aren't much louder than the npp. They sound better for sure, but not much louder. Please post up videos after the install, I have them and I'm considering a secondary cat delete as well.
