Killer B Motorsports "Holy Header" is a 4 into 1 equal length header. Short primary tubes into a single secondary ensures absolute minimum header volume so gases move quickly and turbo response is maximized. Constructed of 321 stainless steel which maintains its strength to a higher temperature than the typical 304 stainless most companies use for cost reasons. A cast 321 stainless merge collector ensures smooth flow and maximum strength. Available either with a 2-Bolt flange for use with factory or direct replacement aftermarket up-pipe or inclusive of an up-pipe and utilizing a V-Band connection.
Fitment on EJ20 turbo models requires use of EJ25 turbo oil pan.
Usually ships in 1 to 2 days.
