SpeedFactory Racing Ram Horn Turbo Manifolds
SpeedFactory Racing ram horn turbo manifolds are high performance, equal-length stainless steel exhaust manifolds designed primarily for high-power Honda© and Acura© drag race applications to spool large turbochargers quickly and generate peak horsepower. Select the model recommended for your vehicle.
Additional details:
* Equal-length runners: Maximizes exhaust gas energy and improves turbo spool time
* Material: Built using thick 1.5 in. Schedule 40 stainless steel
* Welding: Fully TIG-welded and back-purged for internal strength and longevity
* Flanges: CNC-machined from 1/2 in. plate 1018 steel with flat-machined mating surfaces to prevent leaks
* Fitment and usage notes:
-- Application focus: Ideal for high-torque and big top-end horsepower race setups
-- Air conditioning: Standard race versions require the deletion of the factory air conditioning system (though A/C-compatible variants exist for specific street setups)
