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?
