This.

And with that in mind, I am not aware of any dyno shootouts between the Nismo Weldina and the Nismo OEM, so its hard to say which of the two designs is "better".

Here's the real issue; For whatever reason, changing the pipe diameter from whatever it is on either results in a horrendously loud rasp on decel.

I hated it so much that my one attempt to go with a freer flowing Y-pipe convinced me to go back to the welded up Weldina

I know there's also some noise associated with the after market x pipe option some people go with... I love this motor, but it is as harmonious as a busted bagpipe if you have big transitions from one pipe to the next.
