The VA Motorsports Catless Downpipes for the Mercedes-Benz M177 engine turn your GLC63 into something sharper, louder, and more responsive—exactly how an AMG V8 should feel. Designed for the C253 and X253 chassis, these downpipes ditch the stock catalytic converters and give your exhaust system the freedom it needs to really move air. Less restriction, more power, and a sound that finally matches the badge.

Once the cats are out, the twin-turbos spool faster and hit harder. Backpressure drops, throttle response picks up, and you get a stronger pull through the rev range. It’s not just quicker—it’s cleaner. The engine breathes easier, and it shows in the way the power comes on more confidently with each gear.

Now let’s talk tone. The stock system hides a lot of the V8’s personality, but this setup brings it right to the surface. You get a deeper growl at idle, a sharp snarl when you lean on the throttle, and a few crackles and pops on lift-off. It’s raw, mechanical, and genuinely addictive. This isn’t synthetic noise—it’s real exhaust character coming straight from the heart of the car.

Built from 304 stainless steel, these downpipes are TIG-welded and mandrel-bent for clean flow and lasting strength. No coating, no fluff—just solid, high-quality construction built to handle heat and pressure. It’s the kind of upgrade that doesn’t just perform, it lasts.

Pairing them with a proper tune takes things a step further. You’ll see even quicker turbo response, smoother power delivery, and improved thermal efficiency. The whole car feels sharper and more dialed-in, like the drivetrain finally matches the chassis.

If you’re running a GLC63 with the M177 engine and still stuck with the stock downpipes, you’re leaving performance and sound behind. This setup brings it all forward—more power, more character, more fun. VA Motorsports got this one right.

Material

304 Stainless Steel

PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.

  • Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content.  Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
  • Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
  • Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
  • Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
