Custom Manifold Blankets – What’s the Process? How Do We Make Them?
Get the inside look at how Funk Motorsport crafts bespoke manifold blankets — precision heat protection built just for your system.
Why Go Custom?
Every manifold is different — aftermarket, tubular, twin-scroll, V-band. Off-the-shelf solutions don’t always fit perfectly, which is why we offer custom manifold blanket manufacture right here in the UK.
The Funk Motorsport Custom Blanket Process
Step 1: Initial Consultation
We begin by discussing your setup — turbo location, manifold shape, and space constraints. We then provide a quote and request for the manifold, exhaust section or 3D printed replica to be sent to our Essex HQ.
Step 2: Material Selection
Each blanket features a titanium outer layer, silica insulation core, and stainless mesh inner liner for unmatched heat containment. For applications where a heat source will be in direct contact with the outside of the blanket, we utilise our specific Inside Out blanket finish to ensure durability in these areas. For applications where outer carbon fibre outer layer is required for aesthetics, we can incorporate that into our design too!
Step 3: Patterning & Assembly
Using templates or customer-supplied manifolds, our team of machinists create a blanket pattern for perfect fit. Our in-house team then use our signature Funk Motorsport 4-layer blanket construction to assemble each blanket for a perfect fit.
Step 4: Testing & Delivery
Every custom piece is inspected and tested before dispatch, ensuring quality worthy of the Funk Motorsport name. The blankets are then returned to the customer with their manifold, housing or 3D printed replica that was sent in to us. A simple return service!
Benefits of going Custom
- Exact fit for your manifold
- Enhanced under-bonnet protection
- The best performing thermal solution on the market, dramatically outperforming ceramic coating and metallic solutions
- Removable for routine maintenance

How Our Custom Exhaust Blanket Saved Mat Armstrong From Fire!
Our good friends over at the Home Improvements Channel built a bright green Hovercraft to sit alongside Mat’s Lamborghini collection – the ‘Hoverghini’.
In testing the team discovered that the exhaust system came into contact with grass and caused a small fire. The team needed the exhaust to be completely insulated, and fast. We received the exhaust system and got straight to work.
Our team successfully manufactured a bespoke heat blanket for the Hoverghini and the build was successfully delivered to Mat Armstrong, without the risk of fire!

Custom Blankets for a Californian UTV Manufacturer
Speciailist UTV manufacturer, Speed UTV reached out for a custom blanket solution to fully insulate the turbochargers used on their Utility Terrain Vehicles.
When travelling through challenging terrain and environments reliability is key. Our Funk Motorsport custom heat blankets, designed and manufactured by our in-house team, helped to improve exhaust gas flow and shield sensitive components from excess exhaust heat transfer.
Bespoke Exhaust Blankets for Crown Thames River Cruises
The engine rooms of the fleet of Crown River Cruises were in need of high performing exhaust blankets. Crown River Cruises dropped in to discuss their requirements and our team got straight to work on designing bespoke solutions for their exhaust system.
Our team created a series of individual blanket pieces that fit perfectly together to provide full coverage of the exhaust system of the River Boats. The team were so impressed with their performance and ability to be removed for routine maintenance that they were quickly rolled out across the fleet.
