Exhaust Options (T409 Stainless, Mandrel-Bent):

4" Cat & DPF/SCR Race Pipe → Required for air-ride & 2500s

Why It Works

Cloud-based EZ Lynk platform = live tuning, diagnostics, and remote updates.

DIESELR custom calibration = optimized power for 6.7L Cummins.

Race Pipe unlocks air-ride & 2500 platforms.

4"/5" downpipe-back exhaust = lower EGTs, less backpressure.

EGR upgrade = long-term flow + reliability.
