Just spit ballin' here, but since emission deletes are probably now a thing of the past, has anybody tried leaving all the emission hardware in place, and installed an exhaust cut-out ahead of the DPF? Some exhaust would still flow through the factory system, including through all the various sensors, but backpressure would be reduced, and regenerations would decrease, as would EGR and DEF consumption. In a sense, it would "fool" the ECM into thinking the engine was just producing less CO, NOx, soot, so less after-treatment was needed, but it might not trigger a CEL. Any thoughts or experience?
