The ASM exhaust manifolds for the F20/22C engines are some of the highest quality you can buy. The design from ASM results in torque improvements, power (mid range) and weight loss benefits. Dual lower sensor holes included in the design, stainless material with TIG weld finishes to ensure excellent strength and corossion resistance. The 07 version improves on the 04 by upping top-end power by way of slightly different primary and secondary designs and a larger more free-flowing collector joint. 07 is suited for peak power race applications whilst the 04 is suited to street applications.
