GM Duramax LB7-LMM 6.6 Liter SS 12pt Y-pipe bolt kit. Application-specific bolts keep the exhaust Y-pipe securely clamped through repeated heat cycles. The compact 12-point head makes tight spots easier to reach.

Made from polished ARP Stainless, it resists rust and corrosion while delivering strength well beyond Grade 8 hardware.
