A full titanium valved catback in hand heat-anodised titanium, with twin mandrel-bent pipes, a centre resonator, rear valve assemblies and the wireless remote kit supplied.\u003c\/p\u003e\n\u003cp\u003eThe factory GLC63 system is heavy and deliberately restrained for a family SUV, which is a strange fit for the hand-built four-litre V8 underneath it. Going titanium rather than stainless changes two things at once: the system is dramatically lighter, and the note is sharper and more exotic in a way stainless steel cannot reproduce.\u003c\/p\u003e\n\u003cp\u003eMandrel-bent titanium throughout with precision TIG welding, hand heat-anodised in your choice of Gold, Blue or Purple. Supplied complete with the valve assemblies, remote kit and all hardware.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003ch3\u003eFull Titanium Construction\u003c\/h3\u003e\n\u003cp\u003eAerospace-grade titanium through the pipework, resonator and outlets, for exceptional heat tolerance, corrosion resistance and a significant weight saving over both the factory system and a stainless replacement.\u003c\/p\u003e\u003ch3\u003eIndependent Varex Valve System\u003c\/h3\u003e\n\u003cp\u003eRather than reusing the restricted factory valves, this system operates its own dedicated valve assembly with complete travel in both directions. Sealed when closed for a quieter OEM+ driving experience, and fully unobstructed when open for a fully aggressive exhaust tone.\u003c\/p\u003e\n\u003ch3\u003eWireless Remote Kit Supplied\u003c\/h3\u003e\n\u003cp\u003eValve operation is handled entirely by the supplied remote, so the volume is yours to choose rather than the car's. The system does not connect to the factory valve motors.\u003c\/p\u003e\u003ch3\u003eTrue Dual Design\u003c\/h3\u003e\n\u003cp\u003eEach bank of the V8 keeps its own mandrel-bent pipe the whole way back. Where the two pipes cross under the floor they are braced together, which keeps the system rigid over rough roads.\u003c\/p\u003e\n\u003ch3\u003eSignature Titanium Exhaust Note\u003c\/h3\u003e\n\u003cp\u003eSharper, higher-pitched and more exotic than stainless, with cleaner overrun, stronger crackles and a distinctly motorsport tone at high RPM.\u003c\/p\u003e\n\u003ch3\u003eSUV and Coupe Fitment\u003c\/h3\u003e\n\u003cp\u003eBuilt to the correct routing for each body, selected at checkout.\u003c\/p\u003e\n\u003ch3\u003eDirect Bolt-On Fitment\u003c\/h3\u003e\n\u003cp\u003eFits at the factory mounting points and hangers.

Three options are available:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGold\u003c\/strong\u003e - the finish shown in our photography. Warm bronze and gold through the piping with straw and violet heat banding across the bends and weld lines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBlue\u003c\/strong\u003e - deep blue through the piping with gold and violet banding at the bends and weld lines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePurple\u003c\/strong\u003e - rich purple and magenta across the system with bronze shading over the muffler body.\u003c\/p\u003e\n\u003cp\u003eBecause the finish is created by heat, no two systems are identical and the banding will vary slightly from the photographs. That variation is characteristic of anodised titanium rather than a fault.\u003c\/p\u003e\u003ch2\u003ePerformance Benefits\u003c\/h2\u003e\n\u003cp\u003e A sharper, louder titanium note with the valves open\u003cbr\u003e Near-standard volume with the valves closed\u003cbr\u003e Significant weight reduction over the factory system\u003cbr\u003e Reduced restriction through the whole rear section\u003cbr\u003e Sharper throttle response\u003cbr\u003e A strong foundation for a tuned M177\u003c\/p\u003e\n\u003ch2\u003eSound Characteristics\u003c\/h2\u003e\n\u003ch3\u003eValves Closed\u003c\/h3\u003e\n\u003cp\u003e Refined and comfortable cruising tone\u003cbr\u003e Minimal cabin drone\u003cbr\u003e Suited to everyday driving and early starts\u003c\/p\u003e\n\u003ch3\u003eValves Open\u003c\/h3\u003e\n\u003cp\u003e Sharp, exotic titanium tone over the M177 V8\u003cbr\u003e Increased exhaust volume\u003cbr\u003e Stronger overrun crackle and turbo acoustics\u003cbr\u003e More engaging driving experience throughout the rev range\u003c\/p\u003e\u003ch2\u003eSUV or Coupe?\u003c\/h2\u003e\n\u003cp\u003eThe GLC63 was sold as an SUV (X253) and as a Coupe (C253).
