• Straight-Through Design: Non-restrictive muffler design optimizes exhaust flow for improved performance and fuel efficiency
• Dual Rear Exit Configuration: Features 3.5" diameter head pipe and muffler transitioning to 2.75" tail pipes with twin 4.0" polished slash-cut tips
• Bolt-On Installation: Direct-fit design requires no cutting or welding, includes all necessary hardware and factory-style hangers
• Sport Sound Level: Aggressive yet refined exhaust note perfectly matched to the personality of GM full-size SUVs

This system is designed for vehicles with dual rear exit factory exhausts and features a 120.9" wheelbase fitment. Backed by CORSA's limited lifetime warranty, the 21129 delivers professional-grade quality and performance you can hear and feel. Note: Vehicles with single side exit factory exhausts require additional GM components for proper installation.
