****.. this may be the one for me. Great setup. Did you have to do any modification? The Optima Store says that 2014-2015 models need exhaust modification?
I purchased a used ARK-DTS system for my 2015 but was hesitant on attempting the install myself based on The Optima Store note and a video on YouTube where the poster stated an exhaust shop charged him a few hundred dollars to install the system on his 2014-15 because modication was necessary. After watching this new video, I jacked my 2015 up this weekend and within a few hours I had my ARK exhaust on with no modification. It takes a while to get everything lined up and secure but I am extremely happy that I was able to tackle this install myself.
Yep no change for the exhaust to work with 2015. I suspect the guy you are talking about had a modified mid and had to have things fixed. But like you found out, the exhaust on a 2015 model hasn't changed from previous years.
