Honda Conversion Over Frame 4-2-1 Manifold
This 4-2-1 design for the N/A motor has good primary lengths with matched secondaries. I'm looking for best power AND torque. Recent dyno-testing has shown how good this design is with very impressive figures achieved.
All hand-fabricated/TIG-welded with proper, merged collectors plus a V-band connector - it's a quality piece.
IN STOCK NOW.
SYSTEMS: 2.5" bore Re-Packable systems can also be supplied.
SUPERCHARGED INSTALLS: these require a bigger-bore 4-1 design - been asked several times for these - coming soon!
