Show original supplier description

The Speed Engineering True Dual X-Pipe System is constructed from durable 304 stainless steel, ensuring longevity and resistance to corrosion. Its mandrel-bent tubing and integrated X-pipe design facilitate optimal exhaust gas scavenging, leading to improved performance and a more aggressive exhaust note. This true dual exhaust system is specifically designed for 1999-2019 Silverado and Sierra trucks equipped with LS engines (4.8L/5.3L/6.0/6.2L). It is compatible with 4, 6, & 8-speed automatic transmissions. The system is mandrel bent and TIG welded for precision and durability. While generally offering good fitment, some users have reported slight contact with the frame on the driver's side, necessitating minor adjustments during installation.
