1320 Performance 8th Gen Civic SI Header was designed to increase performance and sound of the K20Z3 engine . The header was developed using a proven 4-2-1 Tri-Y design and our step collector design and smooth transitions that delivers power gains almost everywhere in the power band, not just the higher rpm range. Fitment past the subframe and sway bar is perfect with extra clearance available for engine movement.


We start with 44mm primaries that smoothly step into 50mm secondaries and finish with a 2.5 inch exit. Our header are mandrel bent and made from high quality 304 stainless steel tubing and is fully tig welded. We also use a slightly thicker gauge tubing than other manufactures to make sure our product last and we back it up with our 1 year warranty against manufacture defects. 

 

Installation note: It is highly recommended to use a Hasport rear engine mount especially with higher mileage vehicles. The stock mount does not offer the support required to keep the engine movement to a minimum.
