Does a raptor exhaust kit fit on a f250 with the 6.2... I'm fine with some modification but I just want to know basic knowledge if the kits fit pretty similar

 

I doubt it. And if it did, it would take lots of modifications, since the entire truck and system is longer and slightly different routing.

Why not take it to a local muffler shop and have something fabbed up?

I've always gone that route. Honestly I've found it to be price competitive to buying a bolt on kit.
