Is there a active exhaust after market kit that allows you to use the factory harness and factory settings. Just want to get a deeper tone but dont want to lose that feature.
Either look into a resonator delete (H or X pipe) or one of the vendor's replacement mufflers that can still use the AE solenoids and harness (Corsa being one of a few).
Honestly, get an H-pipe. I have a 19 with the active exhaust as well. Once I did the res delete and put an H-pipe in, it was PERFECT for me. A small bit louder in track mode, and a deeper tone from idle all the way up.
