Diamond Eye Manufacturing 663006 Diesel Exhaust Pipe - Kit

Diamond Eye Manufacturing 663006 is a performance diesel exhaust pipe kit engineered to maximize exhaust flow and reduce backpressure in high-output diesel applications. Diamond Eye Manufacturing, based in the United States, has built a strong reputation among diesel truck owners and performance enthusiasts for producing rugged, precision-formed exhaust components built to withstand the extreme heat and stress of turbocharged diesel engines.

This exhaust pipe kit is constructed to deliver a direct-fit installation experience, using mandrel-bent tubing to maintain consistent interior diameter throughout each bend — a critical factor in preserving exhaust velocity and reducing restriction. The result is improved engine breathing, better exhaust gas temperature (EGT) management, and the potential for gains in power and fuel efficiency.

Key Features:

• Mandrel-bent construction maintains consistent pipe diameter through bends for maximum flow
• Reduced backpressure supports improved power output and EGT management
• Heavy-duty materials engineered to handle sustained high exhaust temperatures
• Precision-formed fitment for straightforward, professional-quality installation
• Diamond Eye quality — trusted by diesel performance enthusiasts across Cummins, Duramax, and Power Stroke platforms

The Diamond Eye 663006 exhaust pipe kit is a reliable upgrade or direct replacement for diesel truck owners looking to improve exhaust system performance and durability.
