If I am not mistaken that kit is for show only and does not increase performance on the 2.5.Sorry for resurrecting an old thread. Has anyone successfully gotten the 2.5 dual exhaust? I inquired through my.cadillac accessories quote on the website but haven't heard anything yet. I'll try calling in the next day or two. I think an intake and exhaust to net an extra 10-15 HP would be pretty nice for my gf's 2.5
Bringing it back up again.
Will simple replacing Cadillac ATS Rear Bumper Lower Valance W Dual Outlet be the fix ( Besides buying my own Exhaust system )
