This should be a quick question and answer ...

I just came in to possession of a Monster Sport cat back that had previously been installed on a USDM '03 VIII. I have a USDM IX.

I noticed that on the Monster Sport site it lists a different part number for IX fitment. I assume that this IX specific fitment is for the JDM rear bumper. is this the case? And, since I have the USDM rear bumper, it should fit just like it does on the VIII, right?

I just wanted to verify. I can't bolt it up yet because I need gaskets.
