Show original supplier description
The JH Motorsports JHM-B6S-LTH exhaust headers are a mid-length design crafted from stainless steel, proudly made in the USA. These headers are engineered with larger primary runner sizes to offer improved top-end power without sacrificing low-end torque, making them ideal for enthusiasts looking to enhance their B6-B7 Audi S4's performance. These headers serve as a complete replacement for the restrictive OEM exhaust manifolds and downpipes, connecting directly to a 2.5-inch cat-back exhaust system. The design accommodates both manual and automatic transmissions and retains the use of stock oxygen sensors. However, installation requires significant engine lowering or complete removal. Additionally, it is highly recommended to wrap the headers in the area of the stock manifolds to shield nearby wiring, motor mounts, alternator, and coolant pipes from heat. Care must be taken to properly secure oxygen sensor wires to prevent damage from rubbing or heat exposure. **IMPORTANT NOTICE:** These JHM headers are designated for OFF-ROAD USE ONLY and are not legal for use on highway or street vehicles. This designation applies even if ordered with high-flow catalytic converters. While high-flow cats can reduce certain emissions, they may not meet all legal requirements, especially in California. Purchasers acknowledge and agree that the vehicle will only be used for racing or off-road applications.
