Am I correct in reading this thread that there's an "H" pipe (joining the exhaust paths) under the heat shielding within the piping between the mid-pipe and cats on the nismo?
I was thinking of modding my OE sport exhaust to mimic the Nismo. Now wondering if it would be better to use an "X" in place of the "H" or no balance at all.
