Curious what results other NISMO owners experienced if they replaced their NISMO headers with aftermarket ones. Did you see a significant gain in HP and torque?

Second question is about retaining the NISMO cat back system and just doing a muffler delete coupled with adding high-flow cats (HFC). Has anyone done just this or did you replace the entire system? Did you see a significant gain in HP and torque? Did you go with HFCs?

I'm contemplating just going with HFCs and the rear muffler delete unless there someone experienced a major gain in HP and torque.

I'll definitely be replacing the upper and lower plenums and opting for an UpRev tune.
