With many years of experience building high performance turbo setups 6Boost manifolds are not only built to be one of the highest quality SR20 exhaust manifolds on the market but one that will give you the performance gains you need.

All 6Boost manifolds are individually hand made. They are specifically designed for your application and built around unique "merge collector" design. This means no pipes cross each other and the merge collector directs all gases at the turbine entry.

By using the merge collector design we have seen spool times reduced up to 400rpm and power gains of up to 15% have been achieved. These figures have been proven time and time again in back to back dyno testing.

6Boost manifolds are made from thick wall mandrel bent steam pipe, sand blasted inside and out for a smooth and even finish and then coated in high temperature exhaust enamel that is proven to withstand extremely high levels of heat.

We are so confident in the quality of 6Boost manifolds they even come with a lifetime warranty against cracking and manufacturing defects!

All manifolds come complete with new head and manifold studs, nuts and high quality manifold to turbo gasket included in the price. We also supply new multi layer steel metal head to manifold gaskets.

Available in a wide range of flange patterns including T3 open entry, T3 split pulse divided entry, T4 open, T4 split pulse divided. We can also supply 6Boost high performance race manifolds suitable for Greddy 3 bolt flange and HKS T51R V-band flange. All manifolds are available with single or twin wastegate ports.
