$790.00
Here, you are looking at the Tomei Expreme Equal Length Exhaust Manifold Kit for the 15+ Subaru WRX. This exhaust manifold is the result of 4 years worth of research and development to provide you with a quality manifold. Tomei discovered all the design flaws associated with the OEM manifold and created a quality replacement that will improve the power and the performance while saving weight and producing an aggressive exhaust note.
DETAILS:
Equal length layout
SUS 304 stainless steel construction
2mm piping thickness.
Creates an aggressive exhaust note.
The design removes all the multiple narrow restrictions found in the OEM manifold.
Larger turbo side port ID on the flange compared to stock.
Saves weight.
Improves both horsepower and torque.
Reduced turbo spool time and improved throttle response
Includes new gaskets.
***** FA20DIT Series Exhaust Manifold Kit Unequal Length - TB6010-SB04A
Unequal length runners on the headers achieve the unique boxer engine rumble. The OEM headers restrict air flow resulting in loss of power and efficiency. Tomei headers do not restrict air flow resulting in an increase in power and efficiency.
The OEM headers greatly restrict air flow right after the engine port. Unlike the OEM headers, Tomei headers do not restrict air flow right after the engine port.
The turbo side of the OEM headers severely restricts the flow of the exhaust gas, resulting in loss of power and efficiency. The collector on the Tomei headers were made using the lost wax method. The lost wax method allows the collector pipes to merge smoothly, therefore eliminating any restrictions on the header.
The OEM headers have multiple restriction points which results in poor exhaust flow. Tomei headers have an even 45mm piping from the engine all the way to the turbo, therefore allowing the exhaust gas to flow smoothly.
The OEM headers turboside port is severely restricted by its 33mm port on the header. The slide adjuster on the Tomei header allows users running thicker headgaskets to appropriately extend the header to accomadate for the thicker headgasket. The flange on the Tomei headers is highly rigid, lightweight, and has a stepless flange.
