Definitely not ...
Last stock TSX motor I tuned with an RBC and a header made 243/185 . That was a SSR/DTR 2.4 Header with full 3" given it was in an EG hatch but the motor was still a completely stock 06 TSX longblock ...
Either way nice car
Hell I made 235/188 with an EBay header on a TSX with a stock intake manifold lol
