I have searched a lot and haven’t found a definitive answer. Could the Muffler be mounted in the stock coupe location. Looks like some fabrication would be needed also. I am just looking for an axle back exhaust, and wondered if the IPL Muffler, Infiniti Sport Muffler, or Nismo could be made to work. Thanks in advance.

 

With enough money, yes. Coupe exhaust is very different from a sedan exhaust so it's not a bolt-on mod.
