Punched out 17+ OEM header, 2.5" overpipe, 2.5" resonated front pipe, 2.5" cat back
Then
Replaced cat back to OEM with zero change to performance, knocked down the noise a bit
Then
Replaced 17+ punched out header with Tomei UEL header, zero performance gain, lots more noise though, put OEM header back on because I'm not a **** and care about my neighbors sanity and hearing.
For NA The OEM system flows great once the restrictions are removed.
