The AMG GT 43 has an inline-six turbo engine, and this valved exhaust brings out its best sound. Closed it is quiet and refined. Open it growls, crackles and spools. The system is tuned to avoid cabin drone and uses OEM-style electronic valve control.

Features

  • Grade 5 titanium build
  • 3.0 inch mandrel-bent free-flowing tubing
  • OEM-style electronic valve control
  • Drone-free tuning
  • Precision TIG welds
  • Bolt-on and 100% reversible

The GT43's inline-six needs a different exhaust from the V8 GT63. This page is the Grade 5 titanium GT43 cat-back SKU, not the stainless material choice and not the front-race-pipe bundle. The manufacturer specifies a 3.0-inch layout, electronic valve operation and a bolt-on installation that can be reversed.

Closing the valves routes the system toward a quieter cruising sound; opening them gives the turbo six a deeper note with more spool and overrun presence. The tubing uses mandrel bends and TIG-welded joints. Fitment is limited to the X290 four-door GT43 application here, rather than the unrelated newer two-door GT43.

The 3.0-inch pipe specification and OEM-style electronic valve operation come from the manufacturer's GT43 system details. Its current options include stainless steel and Grade 5 titanium; the SKU here identifies the titanium choice. The titanium part number stays the same throughout this listing; a stainless assembly is a separate material choice rather than a substitute for the product ordered here.

The quieter closed mode suits the four-door car's touring role, while opening the valves gives the turbocharged six-cylinder a stronger exhaust presence. The front free-flow pipes are an alternate bundle rather than included hardware. This page does not sell a GT63 V8 exhaust or the separate two-door GT43 application. Those cars share a badge family but not this exhaust fitment.

Images are from the manufacturer product gallery. That gallery covers other material, engine or configuration choices as well as this SKU; the part numbers and included items below define the product supplied.
