    If these mufflers are from the 140370 cat-back system, that means they are for a 2011-2012 GT. If installed on a 2013-2014 GT the tips would stick out approx 2 inches more than the stock tips. From what I have been told, this is why the 2013-2014 S-type axle backs have a different part number than the 2011-2012 S-type axle backs. That being said, the Borla S-type mufflers are, in my opinion, the best sounding mufflers on the market for the Coyote, and someone should grab these.

    Also - the Summit website says the 2011-2012 S-type axle backs ( part # 11789 ) have 4.0 inch diameter tips and the 2013-2014 (part #11837 ) have 4.5 inch tips.

    completely agreed. i was at the flashlight drags with about 250 cars and i was told by another racer and the guy lining up the cars at the light that i had the best sounding car there.

    They are from the 11-12 kit. I bought my car in june12 so borla was saying to use that kit on the 13 then. I don't recall how far they stuck out. They are definitely IMHO the best sounding mufflrrs for a coyote. I was surprised how loud it was with just the axle backs. I wanna buy another coyote just to hear that sound everyday lol

    Summits site is wrong. 11789 also has 4.5" tips and 2.75" inlet piping. I am running that same axle back on my GT500.

    I figured that was the case. So the '11-'12 kits tips stick out further ( on a '13-'14 ) than the 11837 kit which is made for the '13-'14.
