It carries the most powerful series-production four-cylinder ever built in a low, long four-door shell, and the factory exhaust silences it to suit the car Mercedes thought it was selling rather than the one it actually built. This system replaces the standard centre and rear sections with mandrel-bent 304 stainless tubing and a valved rear muffler, and turns a very fast four-door into one that finally sounds like it.\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\u003e304 Stainless Steel Construction\u003c\/h3\u003e\n\u003cp\u003eMandrel-bent 304 stainless throughout for a consistent bore through every corner, corrosion resistance and a long service life under Australian conditions.\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\u003eClean, strong welds built to survive the heat cycling and vibration a hard-driven turbo four puts through an exhaust.\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.

The A45 hatch and the CLA45 do not share a rear section, and this is the CLA one.\u003c\/p\u003e\n\u003ch2\u003ePerformance Benefits\u003c\/h2\u003e\n\u003cp\u003eA deeper, far louder exhaust note with the valves open\u003cbr\u003eNear-standard volume with the valves closed\u003cbr\u003eReduced restriction through the centre and rear sections\u003cbr\u003eSharper throttle response and a more urgent top end\u003cbr\u003eLighter than the heavily silenced factory system\u003cbr\u003eA proper foundation for a tuned CLA45\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.
