Connecting Pipes
Exhaust and intake connecting pipes bridge the gap between major system components, including the downpipe-to-mid-pipe junction, turbocharger outlet to intercooler, and intercooler to throttle body in forced induction systems. Quality connecting pipes in mandrel-bent aluminized steel or stainless steel maintain full internal diameter through every bend to preserve airflow and reduce backpressure.Popular UpgradesDownpipe-to-cat-back connecting pipes in 3-inch diameter aluminized or stainless steel are the most common exhaust connecting pipes, bridging between an upgraded downpipe and a cat-back system that may not align natively. Intercooler pipes in silicone-connected aluminum or stainless steel tubing are essential for routing boost pressure efficiently in turbocharged builds. Custom-length connecting pipes with slip-fit or v-band ends allow precise fitment in tight engine bays.What material is best for exhaust connecting pipes?Stainless steel connecting pipes offer the best long-t...

Diamond Eye Performance
Diamond Eye Performance manufactures mandrel-bent exhaust systems and components for diesel trucks, with a catalog that spans DPF-back, turbo-back, and cat-back exhaust for Cummins, Duramax, and Power Stroke platforms. CNC mandrel bending maintains full internal tube diameter through bends from 3/8-inch to 5-inch OD in both aluminized and stainless steel, ensuring exhaust gas flow is not restricted by collapsed bends common in lesser exhaust systems.Popular UpgradesDiamond Eye 4-inch DPF-back exhaust systems for the Cummins 6.7L and Duramax 6.6L diesel trucks are the most popular products, providing a meaningful reduction in exhaust restriction over the factory 3.5-inch outlet section. Stainless steel mandrel-bent kits are available for the Ram 2500, Ram 3500, Ford Super Duty, and GM HD truck platforms with direct-fit connections and tip options. Aluminized exhaust kits offer the same mandrel-bent quality at a lower price point for builds in drier climates where corrosion is less of...
