You can expect up to 330 at the wheels. I'm not sure that HFC can bolt up to stock headers, someone with more knowledge can step in there. But if your lookin for performance you can get headers too. Open up the whole system for solid gains. With headers, hfc, solo mach, rotofab, and a pat g remote tune the car dynoed 364/373.
That's my suggestion though, free up the entire exhaust and tune. You'll see good economy gains too! I travel interstate roads a lot, I went from 25-26 bone stock to 26-28. Plus it'll sound saweeet. Solo ftw.
