TurboKraft 911 Turbo Header Primary Exhaust Sets (pair)
Fits:  all 911s 1964-1994 (911/SC/Carrera/930/964)

These are the primary exhaust pipe assemblies as used in our Equal-Length 911 Turbo Headers. 

Equal-length stainless steel tubular headers with 3-into-1 merge collectors, terminating in v-band clamps (matching weld flanges and clamps included).

Available in two configurations:
LEFT/LEFT:  identical pair, exhaust flows out of the heads towards the car's left side 
LEFT/RIGHT:  mirrored (opposite) pair

Sold separately to save you a lot of time and expense when building a fully-custom exhaust systems, such as...

• 934-style center-mount turbo system
• 935-style rear-mount turbo system
  
• SC/RS style exhaust
• wide RSR-style header mating to a GT3 muffler
• etc.

Why equal-length headers?

Equal length primary pipes ensure equal airflow and exhaust backpressure between each of the 3x cylinder heads and an exhaust collector, allowing those cylinders to operate with equivalent loads vs. using headers with different length primaries.  The engine is then working in a more balanced manner, all cylinders equally.

Equal length secondary pipes between the collectors and the turbocharger continue this, ensuring even engine loads bank-to-bank, left (1-3) vs. right (4-6).

Plus, when all the loads are balanced, you can hear it in the exhaust tone:  the engine has a fantastic smooth “tuned” sound.

History:

Equal-length headers aren’t a new idea.  The factory's early long-tube non-turbo headers had equal length primary pipes, as did the headers on many of their competition cars, ex:  SC/RS, 956/962, some of the 993GT2 variants, etc.

Note:  also available in larger or smaller tubing sizes upon request – for larger or smaller displacement engines, motorsport applications, etc.
