record monza

  1. Exhaust
    Just a PSA for the board - the Record Monza is in stock! Someone mentioned they ordered on several months ago and it arrived this past Tuesday. On that info, I ordered one Wednesday, had the dealer confirm that it was an upgraded part for my car on Thursday (yes, that’s the idea!) and it arrived...
  2. Intake And Exhaust
    Just wondering AT WHAT RPM (i.e. exhaust pressure) does the Record Monza spring loaded valve begin to open, diverting some of the exhaust from the muffler to the straight through tips?
