I attached a rough diagram below and it should make sense. The pipe diameter right after the flex sections is 2.4" and the section after the resonators is 2.4". The section in the middle is the restrictive part and thats what got replaced. Sounds clips coming soon.
Also for comparison is a diagram of the OEM Nismo exhaust. The pipe size up front is still tiny but has an H-crossover so its decent.
