Titan Mauler and Two weapon fighting

[DM Mathpro]

I have a question about the Jotungrip ability that the Titan Mauler archetype gives. It states that all attacks are made at a -2 attack bonus. If I wanted to duel wield two handed weapons and took the two weapon fighting feat would that mean each attack is now at a -6?

I think so, as all penalties stack.

Thanks...thinking of making a halfing barbarian that duel weilds great axes...won't be very effective until about 6th level but I see him being very intimidating.

If content from 3.5 is open the "Oversized two-weapon fighting" feat from Complete Adventurer would reduce the penalty for using one-handed weapons in two-weapon fighting

Feat:

OVERSIZED TWO-WEAPON FIGHTING
You are adept at wielding larger than normal
weapons in your off hand.
Prerequisite: Str 13, Two-Weapon Fighting.
Benefit: When wielding a one-handed weapon
in your off hand, you take penalties for
fighting with two weapons as if you
were wielding a light weapon in your off hand
(see page 160 of the Player’s Handbook).
Special: A fighter may select Oversized Two-Weapon Fighting as one of his fighter bonus feats.
