Customers have dyno'd 20-34 hp increases with these and picked up a tenth in ET.
They can be ordered with or without an EGR riser.
They have faster spool up and lower egt's also and work with the OEM or the BD manifolds.
We can ceramic coat these also for improved performance and lower under-hood temps. When ordering the coating please specify Black or Titanium color. Our ceramic coating is a heat coating only, not a rust preventative.
