I know the answer is 90%+ “no”, but I’d be remiss if I didn’t check anyway: any chance you have a source on those “12-to18” speaker upgrade kits that were commonly posted about a year or two ago? I sold my ‘13 GTS for a ‘17 GTC with the exact specs I wanted with the exception of the 18 speaker upgrade. If you don’t have them, I’m SOL right? Regardless, thanks for all of your posts on the exhaust and 9L changes. Super informative.
