But everyone will see when you baseline, with the exhaust put back to stock. Non-nismo will be around 273-77ish consistently state to state dyno to dyno for the last 6 years.

Either way I did want to point out that Soho and Tomei are not the same. Sohos y pipe is 3 inch whereas tomie is only 2.5. I am not saying their is a major difference there but I do remember reading a 3 inch y pipe being recommend on the tomie thread.
