Mazda 6 GY GV GG 1031 2.3L AUG 02 on, Direct Fit Extractor.
Category: Extractors and headers


The MPI Automotive FX-339 is a direct-fit extractor listed to fit the Mazda 6 (GY/GV/GG) 2.3L from August 2002 on. It replaces the cast factory exhaust manifold with a tubular header designed to bolt up in the original location.
This is the header section only — the FX-339 swaps the cast iron exhaust manifold on the Mazda 6's 2.3L engine for a fabricated tubular extractor. Extractors give each cylinder its own primary pipe before they merge, rather than dumping into a shared cast log, and that's where the gains come from on a four-cylinder like this. It's described as a direct-fit part, meaning it's shaped to land on the factory mounting points and pipe up to the rest of the standard exhaust without custom fabrication.
An extractor (header) is the first component off the engine's exhaust ports. The factory cast manifold is cheap to produce and compact, but the merged runners can leave exhaust gas backing up against itself. A tubular extractor separates and lengths the primaries so each cylinder's pulse clears more cleanly. The trade-off is that tubular steel sits closer to the engine bay and is more exposed than a cast unit, so fit and clearance matter — which is why we confirm the build before fitting.
It's listed to fit the Mazda 6 GY, GV and GG body codes with the 2.3L engine, built from August 2002 onward. Series and exact year are not published by the supplier beyond that window, so send us your VIN or build details and we'll confirm the FX-339 matches your car before ordering. Fitment data can be imperfect, so we treat the listing as 'listed to fit', not a guarantee.
