Outstanding Quality
In development for 4+ years to achieve high performance, precise fitment, and outstanding quality that Tomei is known for. Introducing a new first for the 2015+ WRX FA20DIT, the Tomei Unequal Length Header!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.

Better Exhaust Flow
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.
Titan exhaust bandage is included with the Tomei Headers. The exhaust bandage will help prevent heatsoak, resulting in better performance and efficiency. There is no need to pre-soak the exhaust bandage, therefore the exhaust bandage is very east to install.

The Rumble is back!!!
By ajp_wrx October 1, 2020Extremely happy with this purchase. I’ve had it for a well over 4 months now and I would highly recommend. Packaged came undamaged and it had everything you need to install. Fitment was perfect, and install was fairly easy with no modifications needed. I have it paired with just a Nameless Muffler Delete and it sounds amazing! The Subaru rumble really stands out now. Performance wise, I've not seen any dip in performance. I know there are a good number of Subie owners out there who say you'll loose power going from ELH to UEL, but I've not seen it. The car is more alive, sounds more alive, and I couldn't be happier. This is the car I wanted when I purchased my Subie, and now I finally have it.
