On the box it said every motor but the 3.7 for the 09-14 f150 model. Well I bought it regardless of what everything said, and I could not be happier with how it changed my truck. I’ve got more low end power, better sound and better response from what I was previously running. Super easy install less than an hour to remove and install new..I highly recommend even for the 3.7!
Bought this for my 2013 F150 Extended Cab with a 5.0L. I had to replace an aftermarket exhaust that had rusted out in 5 years. This exhaust went on easy (second set of hands help) and sounds great. Not to loud but throaty when its time for business. Put a smile on my face like a school girl.
