Subaru Header & Up-Pipe Combo
Equal Length Header & Up-Pipe ComboThis combo come with an Equal length header, up-pipe, and four new gaskets! |
|
|
Equal Length DesignThe equal length design of the PERRIN header, gives you the best of two worlds. Smoother flow of exhaust to the turbocharger allows turbo to spool quicker giving you horsepower and torque throughout the entire RPM band. While designed to fit to the factory up-pipe, our header will mate with an OEM or aftermarket up-pipe, as well as any rotated turbo kits compatible with the factory header. |
|
Precision CNC Bent Tubing321 stainless steel tubing is CNC mandrel bent and precision welded to perfection. This eliminates the need for a flex joint, which is a major weakness in other up pipes including the OEM one. |
|
Critical Correct SizingThe PERRIN Up pipe inside diameter best matches the OEM exhaust manifold outlet and OEM turbo inlet. This is critical to maintaining exhaust gas velocity increasing turbo spool up. Typically we see 250-350 RPM quicker turbo spool up after installation. Choosing a tube bigger than this can cause the turbo to spool slower. |
|
FlangesPERRIN Flanges are CNC machined from 304 stainless steel and counterbored on the back side to make smoother transitions from heads to tubing and header to up-pipe. |
|
Port MatchingFlange ports sized properly to ensure exhaust coming out of the head has a smooth unobstructed path to the tubes. The ports are not over ported which causes gaskets to burn out quickly. |
|
SoundBecause of it equal length design, the PERRIN header will alter the tone of your exhaust. The exhaust pulses from the engine are equalized and spread out producing a smoother, more refined sound. Some describe the sound to be Mitsubishi EVO like similar to an inline four cylinder engine exhaust.» Listen to the difference |
|
Oil PanMost headers collect on the passenger side of the engine, and due to space constraints, are not equal length, compromising exhaust flow. Because we use the added room provided by the oil pan (only on 2.5L turbo pans), we can create a smooth transition of the header primaries to the collectors, and collectors to up-pipe, providing more power and torque then the competition. See our install kits here. |
|
FinishPERRIN headers and up-pipes feature a brushed stainless steel finish. |
