What about the exhaust loop on the 2012+ models and the evap? Just bought a 15' Rubi 6-speed and am looking at skids as a first mod. If your saying that I can only run an oil pan skid and not have to worry about anything, well then you just saved me a good bit of money.
The EVAP comes with a factory skid and if you really wanted to do anything with it, you'd be better served relocating it than anything. The exhaust loop is a legitimate concern and one that I sometimes forget being that it only applies to 2012-up. I personally don't run a skid to protect mine and have not had an issue but, a good hit to hit could cause damage to your cat and that could potentially be a costly fix. Of course, being so close to your frame rail, it will most likely take the hit first. But, if you want to armor it up, the EVO protek system will take care of it.
