Show original supplier description
The Doug Thorley THY-339Y-C long tube Tri-Y headers are engineered to maximize power output for the 2010-2014 Chevrolet Camaro SS equipped with the 6.0L or 6.2L V8 engine. The 4:2:1 header style is designed to provide a broad powerband, enhancing performance across a wide range of RPMs. Constructed from durable 14-gauge steel with thick 3/8" flanges, these headers are built for longevity. They feature a silver ceramic coating that not only provides a sleek look but also significantly reduces under-hood temperatures and protects against environmental elements. The kit includes all necessary bolts and gaskets for installation, though reducers/adapters and catalytic converters are not provided. These headers are explicitly marked for RACE USE ONLY and are NOT LEGAL FOR STREET USE ON POLLUTION CONTROLLED VEHICLES. The product is backed by a Limited Lifetime Warranty to the original purchaser and is proudly 100% American made.
