Every flaw of the OEM header has been addressed and improvised during the development of the Tomei header, resulting in power gains you can feel throughout the powerband of the car.- 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.
- 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 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 easy to install.

Good bang for your buck, great quality.
Works great. Most of it is metal and works as a heat sink. Came with two fuses and the adapters for smaller or larger Guage wires. Fit very well and easily for our choice of installation and was a great price.

Good for under the hood
Pretty good heavy duty block. It's got the rubber grommets for the smaller wire if needed.
