Secondary Downpipes BMW 760i G70 S68

Secondary Downpipes for the BMW 760i G70 4.4i V8 S68 are engineered to optimize exhaust flow by replacing Stock BMW secondary (Lower) catalytic converters. With our 760i G70 secondary Downpipes you can replace only the secondary (lower) Stock catalytic converters and keep the primary (upper) Stock catalytic converters (No Check Engine Light). Secondary downpipes are a transformative upgrade for the BMW 760i G70. By enhancing exhaust flow, they unlock additional performance, elevate the exhaust note, and add a layer of personalization to this luxury sports sedan. 

• High Quality Materials: Sandblasted Stainless Steel (T304) with TIG welding for exceptional durability, 3 years warranty;
• Boost Performance: The improved exhaust flow lead to gains in horsepower and torque, especially when paired with a performance tune that optimizes the engine for the freer-flowing system;
• No Check Engine Light: By retaining the primary catalytic converters, the vehicle remains partially compliant with emissions regulations and may avoid triggering check engine lights (CEL) related to oxygen sensor readings. 
• Enhance Sound: Secondary downpipes result in a deeper, more aggressive exhaust note, giving the BMW 760i a sportier sound profile that complements its high-performance V8 S68 engine.
