It replaces the exhaust from the catalytic converter back with a single 3\" front pipe section running into a straight through centre muffler, then twin 2.5\" rear pipe work, 5\" round rear resonators and 5\" polished round rolled-in tips. All of the pipe work is mandrel bent and the system is built from brushed finish 304 stainless steel. It runs Varex remotely adjustable mufflers, and XForce's SmartBox control unit can be added to control them.\u003c\/p\u003e\u003cp\u003eThe sizing is worth a look. A single 3\" section feeds the centre muffler, and the twin 2.5\" rear pipe work behind it adds up to more cross-section across the two paths than the single 3\" pipe ahead of it, so the split is not a step down in flow. Mandrel bending earns its place on a layout like this, holding the full internal diameter through every corner instead of pinching it at the bends, and a straight through centre muffler does its silencing as the gas passes along the body rather than reversing it through chambers - both consistent with the flow-focused pipe sizing. With remotely adjustable Varex mufflers, and the SmartBox control unit added, the note becomes a setting you pick as you drive: a quieter position for a long highway stint, an open one when you want to hear the 5.3L V8.\u003c\/p\u003e\u003ch4\u003eFeatures\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVarex remotely adjustable mufflers - set the exhaust note on demand\u003c\/li\u003e\n\u003cli\u003eSingle 3\" front pipe work splitting to twin 2.5\" rear pipe work after the centre muffler\u003c\/li\u003e\n\u003cli\u003eStraight through centre muffler with 5\" round rear resonators\u003c\/li\u003e\n\u003cli\u003e5\" polished round rolled-in tips\u003c\/li\u003e\n\u003cli\u003eAll mandrel bent pipe work in brushed finish 304 stainless steel\u003c\/li\u003e\n\u003cli\u003eXForce SmartBox control unit can be added to run the Varex mufflers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003cp\u003eGMC Sierra 1500 5.3L V8, 2019 to current, and the Chevrolet Silverado 1500 5.3L V8.
