⚠️ Important Fitment Notes
-
Designed only for use with SPDZ1 Long-Tube Headers (not compatible with factory manifolds or stock mid-pipes)
-
Most 6.0L applications use a 2-into-1 exhaust system – this Y-Pipe is not compatible with that setup.
-
For 6.0L 2-into-1 systems, our SPDZ1 X-Pipe Kit may be used, but fabrication will be required.

Unlike budget alternatives, SPDZ1 Y-Pipes are dyno-tested, precision-bent, and guaranteed to fit without the headaches. Every pipe is built from true 304 stainless, TIG welded for strength, and designed to give your truck or SUV the performance sound and durability it deserves.
