Honda K Series Sidewinder V-Band Exhaust Manifold

Here is our new K Series Sidewinder.

One of the design aspects we really wanted to have was keeping the turbo square to the engine and not having the inlet of the turbo facing towards the centre line of the engine.

Also we wanted to have the best in class for boost control without going to a massive wastegate. The manifold will come machined to suit the 44/45/46mm waste range yet also allow the customer to cut the flange off and run a 50mm unit if desired. The internal sizing and flow will still out flow a 50mm unit.


We also believe this feature to be an industry first: a 4" down pipe with clearance for LHD brake master cylinders and their booster. It also allows wastegate plumb back and provision for a wideband to screw in.
On the manifold there is a mount near the turbo flange that allows the customer to make an extra brace to support the weight of the turbo system.

On the dump and manifold there are provisions to run a brace to keep the weight of the dump off the V-Band flange. The dump is machined for a 3.5" V-Band flange to make it easy for a full 3.5" exhaust or 3" system to be fabbed up. The manifold will also come with our innovative 50-55mm V-Band mounting system to allow turbos as small as a G25 through to a 6870 or down the track we will be releasing a weld on piece that will allow 70mm V-Band flanges to go on so you can run the big boi turbos like @garrettmotion G40 G42 and G45's or @precisionturbo 6870 all the way up to 8685's.

At ARTEC we have revolutionised the turbo manifold industry with our industry leading SUS347 stainless steel investment cast manifolds.

All of our manifolds are engineered and designed from the ground up, CFD simulated and, most importantly, tested in the real world to achieve maximum flow and heat dispersion. The cast stainless construction allows us to maximise flow and efficiency by having smooth merging angles and eliminating any restrictions from tight radius bends or runners.

The result is a truly optimised manifold with consistent performance, resistant to heat pooling and cracking, plus a beautiful smooth exterior finish.

Designed and tested in Australia, backed with a lifetime warranty.
