Flexi-Repair

What can you do if your Flex Pipe on your vehicle is leaking or has broken?
All flexibles on car exhaust will someday fail on you, this is not due to poor design or a manufacturing fault. Rather more so the Job and purpose of the Flexi on an exhaust reaching an end. The Flex Pipe on your exhaust absorbs the movements from the engine, this as a results reduces knocking or banging of your exhaust against the body of the Vehicle. Flexi pipes aid with expansions of exhausts, due to high levels of heat produced by the gasses exiting your engine. This also helps reduce the chances of your exhaust rubbers and brackets getting damaged due to strain from constant vibration.
These Flexible sections come in many different designs and are referred to in a few different terms, generally referred to as a braided flexible, Interlock Flexi (double layered or Triple layered flexi), DPF Flexi (Welded directly on a DPF), Down Pipe Flexible or just a Flexi. Exhaust Flexibles are generally positioned close to the engine of vehicle, either immediately after the manifold downpipe, DPF down pipe or after a turbo downpipe.
Our Stainless 304 Exhaust Flexi are different to others, simply because our flexibles are 100% stainless steel. What you will find with some suppliers is that the flexi itself is stainless but the ends are mild steel, which as a result with only rust away eventually.
We refer to our exhaust flexis as ILOK (interlock), these consist of 3 layers, the outside is a woven or braided stainless steel, under this there is a ribbed / corrugated flexible and finally on the inside the last layer is an interlocked polylock flexible. These combined produce a robust product which will last longer than just the cheap double layered flexis.

 

 ‘Do I need to replace the entire section?’ The answer is no, so long as you are able to weld in situa (being able to weld or clamp the flexi whilst it’s on the vehicle) or are able to remove the factory exhaust section off the vehicle to be able to carry the work out on a work bench.

On some vehicles, manufacturers place the flexi section immediately before/after a catalytic converter or a DPF. These particular flexibles have to be replaced with a WELD ON flexi as there is no pipe to clamp on to. However, if your car has a flexible with enough straight pipe on each side, you can easily cut the old broken flexible and replace it with one of our CLAMP ON flexi joints.
Our Clamp On flexibles are made to order on a daily basis as we have a strict policy to maintain high quality British Made products, we therefore do not import cheap versions from abroad. We use 304 Stainless Steel collars which are modified using specialist tooling to fit the OD of your pipe.

 

 

At Exhaust Parts UK we can manufacture exhaust flexibles made to order. We can supply a full range of 100% stainless steel flexi joints ranging from 1.5” / 38mm to 5” / 127mm diameter. Flexis are measured form the end caps on the flexible unit.

How the flexibles are measured?
Below is a table to demonstrate how the flexibles are measured.
Weld on Exhaust Flexis are measured from the end of the stainless cap on each side.

Clamp On Flexis are measured including the end collars that we have welded on for you. To work out the actual flexible length subtract 4” / 100mm from the total clamp on measurement.
