BUILT TO ENDURE
Sound may be the primary feature of iE’s Catback Exhaust, but durability and reliability play a significant role. This catback is crafted from mandrel-bent T304L stainless steel, featuring hand-TIG-welded joints and several structural details that enhance its strength and integrity. The stamped, multi-wall muffler prevents warping, while reinforced hangers ensure a secure mounting. Strength-boosting bridged piping distributes weight, reducing stress and vibration. Wide-width stretch clamps ensure tight and leak-free connections.
