Valach Exhaust Bends


Valach Stainless Steel Exhaust Bends

Great for your straight pipe setups or to start a more elaborate exhaust solution

Always sold single, make sure to get the number of bends needed in total for your project

Make sure to tell me in email or per phone call should you need the end of your exhaust bends flanged/ widened by us to fit the Valach Flextubes. They otherwise come unwidened to offer you a better aesthetic on your straight-pipe out setups. I can preflange your complete setup for you if you like


Length may vary from the photos!

In case of the VMM60/70/85/120 and 140 bends: Keep in mind that since you position them in the flange you can spin them anyway you want and even cut them at the base to where you can stick them in the flange at high angles. Meaning a bend can give you a wide range of “degrees”, a 90degree does not have to remain a 90 degree bend, you can add a lot.


In order to add components aft the exhaust bends:

To combine Silencers with Exhaust Bends, to simply extend the exhaust bend on the motor to reach a desired exhaust port location on your model etc we offer flextube solutions.


Two styles available: solder on and clamp on. Both work great but need some know-how.

The idea is as follows: you do NOT want any stress cracks, and they will happen should you solder pipe to pipe. That is where the flextubes come in, they act not only as a flexible tube that allows you to individually align your setup, they "detach" the motor from your exhaust solution in the sense of decoupling vibrations.

We pride ourselves in being able to bring solution from many German manufacturers together under one roof here at Aeroscale, but that means that there are in this case 2 styles of tubes to know about.

The Solder-on/Springload kind and the Clamp-on

Let's start with the Clamp-on:

We are looking here at a flextube that is "woven", it will expand in diameter when you rotate it one way, will tighten the other. And here is how it works. You expand it all the way and place the clamp where it is needed. Now slide the tube with clamp in place over the end of the exhaust bend or the entry port of your silencer. Grab the end of the flextube by the clamp and twist to tighten. If you add some teflon tape or high-temp seal making product like Permatex beforehand you will have a perfect and tight seal and fit.

Solder-on/ Spingload:

Those require some soldering.
Slide the flextube over the bend or silencer entry port and mark where you want the flextube to stop/end.

Grab a large enough washer and cut it in half. You now have two “Rainbows”.

You solder one half of the washer to each side of the bend (top and bottom when viewed from the side), right where you want the flextube to stop.
Now apply Permatex or other heat resistant sealant product to the bend in good amount and slide the flextube in place

Grab two springs and two pieces of wire.

Mount the one end of the spring to the washer, tie the wire to the other end spring, pull the spring towards the flextube and wrap the wire around the coils of the flextube as and where needed to position and maintain spring pull.

Repeat on the “other side” of the bend, you now have springs on “top and bottom” pulling the flextube in.

This makes for the following exhaust solution examples:

Valach VM120 opposed twin/Boxer -

a) Clamp-on


2 x Valach Exhaust Flange VM60, VM70, VM120, VM140

4 x Spring Clamp 20mm

2 x Valach Flextube Exhaust Extension Exhaust Flextube 20mm iD 200mm length Clamp-on OR Exhaust Flextube 20mm iD 300mm length Clamp-on depending on what length you require

1 x for example VM120 / VM140 front exit 2-in-1 Y-Silencer

if no silencer is needed you only need 2 Spring Clamps

b) Solder-on (needs washer, wire, 2 springs)

2 x Valach Exhaust Flange VM60, VM70, VM120, VM140

2 x Exhaust Flextube 20mm iD 300mm length Solder-on/ Springload

1 x for example VM120 / VM140 front exit 2-in-1 Y-Silencer
