Ford BF GT V8 4V Sedan 2.5in L & R With Extractors Hotdog/Muffler (MKFD0121) Fits FORD. Fast shipping.
Category: Extractors and headers


Listed for the 4V GT, the MPI Automotive MKFD0121 is a 2.5in left-and-right extractor system for the Ford BF GT V8 4V Sedan, finishing through a hotdog-and-muffler rear. The 4V designation marks it as the four-valve BF GT build, routed down each side of the sedan off tubular extractors.
The MKFD0121 is listed specifically for the Ford BF GT V8 4V Sedan — the four-valve BF GT. That 4V cylinder-head context is why it's its own listing rather than sharing a general BF fitment. It uses a left-and-right 2.5in layout, running a separate pipe down each side of the sedan, with a hotdog resonator and rear muffler for a present but streetable note on the GT.
Tubular extractors replace the cast manifolds with runners off each port, easing the merge at the heads. On the MKFD0121 they feed the 2.5in L-and-R pipework into a hotdog and rear muffler — a complete engine-back package matched together. We have no published flow or sound figures, so the case for it is the BF-GT-4V-specific build and its 2.5in sizing rather than a measured number.
It is listed to fit the Ford BF GT V8 4V Sedan. Confirm your exact BF GT build, the four-valve head and any prior exhaust changes with the workshop before ordering, as feed data can be imperfect.
Oak Flats Muffler Men supplies and fits BF and Falcon extractor systems in-house across the Illawarra. We confirm extractor access at the heads, then route both sides of the 2.5in L-and-R run and locate the hotdog and rear muffler under the sedan. At an RRP of $4,906.36 it's a build-to-order package; send your BF GT details for fitment confirmation.
