Applications
Exhaust Construction |
 |
Bayonet Hangers: Swaged bayonet ends lock your exhaust components into place for the most secure installation possible. Other manufacturers use less expensive bent hangers that allow tubes and parts to slide from side to side, causing premature wear and damage.
Welded-on hangers: Every hanger is welded on each side to ensure a stronger connection, compared to the other manufacturers who use only inferior floating hangers.
Band Style Clamps: Premium quality band clamps are used on critical joints to provide the tightest, leak-free seal possible. Other systems use common less expensive U-bolt clamps.
Mandrel Bent: All aFe tubing is mandrel-bent. Mandrel bending ensures the tubing maintains its shape and size, providing smooth, unrestrictive airflow. Standard tubing can lose as much as 20% of its diameter in sharp bends.
