Why Do I Need An External Wastegate Blanket?
External wastegates sit in one of the hottest parts of a turbo setup. During hard road, track, drift or dyno use, they can radiate heat into nearby wiring, vacuum lines, boost control hoses, brake lines, intake pipework and bodywork. That heat can make the engine bay harder to work around and can shorten the life of nearby components.
An external wastegate blanket works by helping to contain radiant heat at the wastegate instead of letting it spread through the engine bay. That helps protect nearby parts, reduces the chance of heat-related wiring or hose damage, and makes the turbo area safer to work around once the car has cooled.
This is best treated as part of the full turbo heat-management system. If you are controlling heat around the manifold, turbo and downpipe, pair this with an Exoracing turbo blanket, Exoracing exhaust wrap and Exoracing heat reflective tape for nearby panels, intake parts and wiring.
Which Wastegate Blanket Size Do I Need?
Choose the blanket size that matches the external wastegate size. If you are not sure, check the wastegate brand/model specification or measure the wastegate before ordering.
| Blanket Size | Choose This If | Finish Options |
| 38mm | Your external wastegate is listed as 38mm. | Titanium or carbon |
| 44mm | Your external wastegate is listed as 44mm. | Titanium or carbon |
| 50mm | Your external wastegate is listed as 50mm. | Titanium or carbon |
| 60mm | Your external wastegate is listed as 60mm. | Titanium or carbon |
Titanium Or Carbon Finish?
| Finish | Best For |
| Titanium | A classic motorsport heat-management look that pairs well with titanium exhaust wrap and turbo blankets. |
| Carbon | A darker finish for builds where you want the blanket to look more subtle in the engine bay. |

External Wastegate Blanket Installation Guide:
Fitting is straightforward, but always wait until the wastegate is completely cool before touching it. Wear gloves when handling heat blankets because loose fibres can irritate skin.
- Let the turbo system and wastegate cool fully before installation.
- Check that you have the correct blanket size for your external wastegate.
- Position the blanket around the external wastegate body. The shape should make the correct orientation clear.
- Route the supplied locking wire around the blanket hooks.
- Pull the locking wire tight enough to hold the blanket securely without crushing or distorting it.
- Check clearance around boost hoses, vacuum lines, wiring and the screamer pipe or dump tube.
- After the first heat cycle, recheck that the blanket is still secure and has not moved.

Frequently Asked Questions
Which size external wastegate blanket do I need?
Choose the blanket size that matches your external wastegate size: 38mm, 44mm, 50mm or 60mm. If you are unsure, check the wastegate manufacturer's specification before ordering.
What is the difference between titanium and carbon finish?
The main difference is appearance. Choose titanium if you want the classic motorsport heat-management look, or carbon if you want a darker finish.
Does it include the locking wire?
Yes. Each Exoracing external wastegate blanket includes stainless locking wire for installation.
Can this be used with a turbo blanket?
Yes. A wastegate blanket and turbo blanket work well together because they control heat from different parts of the turbo system.
Can oil or coolant damage the blanket?
Yes. Keep the blanket away from oil, coolant and other contaminants because they can damage the material and may create a fire risk in extreme heat.
Notes:
- Choose the correct blanket size before ordering.
- Allow the wastegate to cool fully before fitting or adjusting the blanket.
- Wear gloves when handling the blanket because loose fibres may irritate skin.
- Do not contaminate the blanket with oil, coolant or other fluids.
- Professional installation is recommended if the clearance around the wastegate is tight.
