Speed Engineering 1-7/8" Longtube Headers & Y-Pipe Full Kit for 2007–2013 Chevrolet Silverado and GMC Sierra 1500 4.8L, 5.3L, 6.0L, 6.2L applications.
This complete bolt-on system replaces the restrictive factory exhaust manifolds and mid-pipes with free-flowing stainless longtubes and a 3" off-road Y-pipe that connects directly to the existing cat-back location. Designed for improved exhaust flow, increased horsepower, and a deeper, more aggressive exhaust tone while maintaining long-term durability.

⚠️ Note: Rear (downstream) O₂ sensors are not used. A check-engine light for catalyst efficiency will appear and must be disabled via PCM tuning.

Kit Includes

(1) Pair of stainless steel 1-7/8" Longtube Headers
(1) 3" Off-Road Y-Pipe / Connection Pipe
(1) Set of Zinc-Coated Header Bolts (or stainless ARP bolts if selected)

Plug Wires and Sleeves can be added to the kit if selected.

For me the ball joints came bolted in on both upper control arm.
The also make it easier for future bushings replacements, by not being pressed fit. They also have grease ports to grease the bushings.
