SUPER MANIFOLD with CATALYZER R-SPEC is more advanced and upgraded product of SUPER MANIFOLD with CATALYZER GT-SPEC. By removal of the catalyzer at the exhaust manifold, we could have a substantial reduction of the exhaust pressure. We also redesigned layout of front pipe with HKS metal catalyzer (this product comes with front pipe that passed Japan exhaust regulation).

Features

It will have great performance around 3,000PRM because we adopted 4-2-1 layout manifold which improves output at normal and high RPM range. And also because of the metal catalyzer, it will perform great at high RPM because of the less exhaust pressure. SUS304 is used for the main material to have a good durability to perform better at circuit drive. There is no need for parts modification for installation. So it will take about 1hr to 2hrs in cool situation.
