If you wish to purchase a Custom Manifold from Just Engines please add this product to your basket, checkout, and then send us a sketch with dimensions (by email (jpg) or post). Once received an engineer will contact you to discuss your exhaust and agree any additional charges before manufacture.  10 to 15 days later you will receive a custom built manifold specially made for your project.

We understand that it can be difficult to know exactly what dimensions our engineers need to manufacture a manifold, so we have created some pdf files for you to use. You can either use them as guides or download them, print them and return them to us completed.

For Swan Neck manifolds – to convert side exhaust to rear exhaust, use – swan1.pdf and swan2.pdf

For Rear exhaust manifolds use – rear1.pdf

For 90 degrees manifolds ‘cranked’ use – 90bend.pdf

Please take a look at the examples below.

Please note that the £10 charge is just a place holder, when you checkout the total cost will be incorrect, but we will agree any additional charges before manufacture.

Description

Example exhaust headers and manifolds, all made by us for our customers:

Swan Neck 1

‘Swan neck’ (side to rear) manifold

For an upright mounted engine in a delta

(Paul Brundrett’s Rapier)
Swan Neck 2

Fred Cooper’s ‘Swan Neck’ setup
Down Under 1

Richard Norris’ Moki + manifold, connects to a quiet silencer inside the cowl and airframe.

90º but ‘clever’ so that the outlet goes into the centre of crankshaft (so pipe or silencer stays central in (or outside) of the model – making balancing easy!

On this example, the engine’s side thrust was also built into the flange – that’s why I call it ‘clever’!
Down Under 2

90 degree, side thrust and down thrust, centring pipe in mid fuselage

Laurence Peake’s Mistaken Identity
Twin

Custom manifolds (and silencers) for double engine setup.
Water Cooled

Water cooled manifolds for marine use (also with ’tilt’)

1 review for J’EN Custom Manifold

  1. Shane Turner (verified owner) –

    I’m very impressed with my new custom header, the quality and workmanship is much better than I could have hoped for, seems a shame to hide it behind the cowl!
    It fits like a glove and at a very reasonable price I highly recommend.
