DEI Speed Sleeves FAQ

What is exhaust wrap made of and does it contain asbestos?
DEI exhaust wrap rolls are primarily composed of composite fiberglass material that is treated with a proprietary coating developed by DEI to help increase the wraps thermal resistance when compared to the other brands. DEI wraps contain NO ASBESTOS!

Will wrapping my exhaust pipes make it rust?
If the exhaust pipe is made of mild steel, it may rust over time with or without exhaust wrap. If you are going to wrap any kind of steel pipe we recommend using our HT Silicone Coating to seal and protect the wrap and even the pipe you are wrapping. In addition, HT Silicone provides added thermal insulation and increases the longevity of your wrap.

Will the exhaust wrap work on my stock exhaust system?
Yes, it is perfectly compatible with all exhaust systems from Cast Iron to Stainless Steel. Not only that, but you can safely use the wrap on any kind of tubing metal or aluminum. This includes piping on an intercooler, turbo down pipe, air intake and intake manifold.

How are Speed Sleeves fastened?
The locking fasteners are clamps that you crimp together holding the material. You will place a fastener 3" - 4" apart then crimp using a pair of pliers.

Is it possible to use HT Silicone coating on Speed Sleeves?
You can use the HT Silicone Coating but since the Speed Sleeves are likely to be installed while the exhaust manifold is on the vehicle, there could be over spray from the HT Silicone Coating. This can effect the cosmetics of the engine compartment and possibly contaminate oil, antifreeze, or air filters.
