Nismo H pipe different for manual and auto models?

Had a H pipe fabricated in 2.5 inch and used a borrowed nismo H pipe so I didn't have to take mine off of the car. Didn't even think to check if they were the same, unfortunately for me they're not. The one we used as a template is significantly shorter and the angle of the bends slightly different so my new fabricated 2.5 inch H pipe didn't fit. I'm having it lengthened so that it will fit. Am I the only one that didn't know that Nismo H pipes are different. Either Nissan changed the design or they're different for manual and auto models?

I got the Nismo R-Tune CBE and it fit right on. I don't know what the diameter is.

The diameter is 2 1/2". :tup:

Thanks, that is good to know.
