A full Titanium Valved Catback Exhaust for the Mercedes-AMG CLA45, built entirely from titanium with a heat-treated blue finish and a valved rear muffler.\u003c\/p\u003e\n\u003cp\u003eTitanium is roughly forty per cent lighter than stainless steel at the same strength, and on a system this long that is real weight taken out of the back half of the car. It also holds heat differently, which is where a titanium system gets its characteristic harder, higher edge on overrun.\u003c\/p\u003e\n\u003cp\u003eThe blue running through the pipework is not a coating. It is the colour titanium takes on when it is heat treated, which is why no two systems come out identical and why it deepens rather than fades with use.\u003c\/p\u003e\n\u003cp\u003eThe valves are operated from a supplied remote, so the volume is your decision rather than something the throttle position decides for you. Closed, it is close enough to standard for an early morning. Open, it is a different car entirely.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\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 quiet running, and fully unobstructed when open for maximum flow and volume.\u003c\/p\u003e\u003ch3\u003eFull Titanium Construction\u003c\/h3\u003e\n\u003cp\u003eTitanium end to end, not a titanium tip on a stainless system. Substantially lighter than the factory exhaust, and the weight comes out of the rear of the car.\u003c\/p\u003e\n\u003ch3\u003eHeat Treated Blue Finish\u003c\/h3\u003e\n\u003cp\u003eThe blue and violet running through the pipework is the titanium itself, brought out by heat treatment rather than applied on top of it.\u003c\/p\u003e\n\u003ch3\u003eValved Rear Muffler\u003c\/h3\u003e\n\u003cp\u003eA compact rear silencer with the valve built in, so the system opens and closes as one rather than fighting a restriction further down.\u003c\/p\u003e\n\u003ch3\u003ePrecision TIG Welded\u003c\/h3\u003e\n\u003cp\u003eTitanium is unforgiving to weld and every joint on this system shows it, with clean stacked welds throughout.\u003c\/p\u003e\n\u003ch3\u003eDirect Bolt-On Fitment\u003c\/h3\u003e\n\u003cp\u003eFits at the factory mounting points and hangers, using the original rubber isolators. No cutting and no fabrication.\u003c\/p\u003e\n\u003ch2\u003eChoose Your Titanium Finish\u003c\/h2\u003e\n\u003cp\u003eThe colour on a titanium exhaust is produced by heat, not by paint or coating, and it runs through the pipework and muffler body as one continuous finish. Three options are available:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBlue\u003c\/strong\u003e - deep blue through the piping with gold and violet heat banding across 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\u003e\u003cstrong\u003eGold\u003c\/strong\u003e - warm bronze and gold dominant, with blue and violet coming through at the bends and weld lines.\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\u003eA deeper, harder exhaust note with the valves open\u003cbr\u003eNear-standard volume with the valves closed\u003cbr\u003eSignificant weight saving over both the factory and stainless systems\u003cbr\u003eReduced restriction through the centre and rear sections\u003cbr\u003eSharper throttle response and a more urgent top end\u003cbr\u003eA finish that no stainless system can reproduce\u003c\/p\u003e\n\u003ch2\u003eWhy Choose Titanium\u003c\/h2\u003e\n\u003cp\u003eTitanium is the material every factory motorsport programme reaches for, and the reasons are simple. It is far lighter than stainless steel for the same strength, it tolerates heat better, and it does not corrode. On a road car the weight saving is what you feel first, and the finish is what everyone else notices.\u003c\/p\u003e\u003ch2\u003eC118 Only - Check Before You Order\u003c\/h2\u003e\n\u003cp\u003eThis is a full rear-section replacement, and a rear section follows the \u003cstrong\u003ebody\u003c\/strong\u003e rather than the engine. It is shaped for the \u003cstrong\u003eC118 CLA45 four-door coupe\u003c\/strong\u003e and nothing else.\u003c\/p\u003e\n\u003cp\u003eOur M139 \u003cstrong\u003edownpipes\u003c\/strong\u003e cover the A45, the CLA45 and the GLA45, because those follow the engine and all three share it. \u003cstrong\u003eThis catback does not.\u003c\/strong\u003e A W177 A45 is a hatch and an H247 GLA45 is an SUV — different floor, different silencer position, different exit geometry.

Exhaust sound will vary depending on whether a factory or aftermarket downpipe is fitted.\u003c\/p\u003e\n\u003cp\u003eCheck your local road rules before fitting.
