    A few questions:
    We can run dumps with bullet-style mufflers but cannot have a full exhaust (IE y-pipe and catback) with a cutout open?
    Is E85/98 considered "pump gas?
    Alternator relocation allowed to where the A/C compressor is?
    Does the battery box in the trunk need to be vented if it is a dry cell (optima) battery?

    Thanks!

    Exhaust cutout may be open on y-pipe/single exhaust vehicles but must pass through a muffler (IE bullet style muffler in intermediate pipe and cutout after bullet style muffler).

    E85/98 is not allowed in Street Stock. Pump gasoline only.

    Alternator may be relocated.

    AFAIK NHRA still requires drycell batteries to be in a battery box vented to outside of the vehicle.
