Alright here is the email I fired off to Magnaflow, we'll see what they say... "Hi there, recently I have ordered your exhaust system #15218, the system should be arriving at my door any day now. The question I have is in regards to the installation of this system on a 2013 Explorer Sport w/tow package. This morning I stumbled across a fellow forum member who has brought two VERY important issues to light and would like some clarification if possible. His post reads as follows "Warning for those looking to pickup the new Magnaflow for the XSport.
#1 it is not a bolt on like the instructions depict. You will need to hack your stock exhaust off after the cat. Stupid IMO when they could have just offered a kit that either A) replaces the cat or B) has hi-flow cats that does to a flange.
#2 the kit will NOT fit if you have a factory tow package. They designed the system for one w/o it. I am lucky enough to live 5 min. away from their engineering center so I brought my car into them to show them and they agreed, fixed mine and hopefully redesign it. Basically the drivers side muffler hanger needs to be reversed. Simple enough for anyone with a grinder and welder to fix but crappy for those without access."
Obviously you can see the reasons for my concern as it says nowhere in the installation manual that there will need to be any modification to the stock exhaust system aside from simply unbolting and bolting up the new one. Secondly if this kit will not fit with the tow package, why is this not listed anywhere and who is responsible for the cost of modification to the new system? If you can confirm or deny any of the above and provide a solution this would be greatly appreciated.
Thanks."
