Exhaust & Intake Connecting Pipes for Performance Builds

Exhaust & Intake Connecting Pipes for Performance Builds

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 Upgrades

Downpipe-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-term corrosion resistance and are the premium choice for any exhaust build that will see wet or salty road conditions. Aluminized steel is a cost-effective alternative for builds in dry climates. For intake and intercooler applications, aluminum connecting pipes with silicone coupler junctions are standard, providing lightweight and rigid boost routing with flexible mounting points.

What diameter connecting pipe do I need?

Matching the connecting pipe diameter to the adjacent system components is essential. Most bolt-on cat-back systems and downpipes use 2.5-inch or 3-inch pipe, while high-output diesel and large-displacement builds may use 3.5-inch or 4-inch connecting sections. Measure the outlet diameter of the upstream component and confirm the inlet size of the downstream component before ordering a connecting pipe.
