DHD 2" x 100' Black Fiberglass Exhaust/Heat Wrap

Controlling under hood temperatures is crucial to protect electronics and rubber/plastic components. Its no secret our diesel engine bays are packed with hoses and electronics. Protect them by adding heat wrap to exhaust components. Up-pipes and downpipes are excellent candidates for heat wrap.

Features:

• 2" x 100ft Roll
• 1.5mm Thick Fiberglass

Notes for Installation:

• Use the right product. This header wrap is 1.5MM thick fiberglass, which is ideal for most street or race cars, trucks, bikes, or boats. It substantially insulates exhaust parts while allowing some of the heat to escape, preventing overheating and fatigue (or "burn-out", as it's sometimes called). Do not double wrap, and do not use too much overlap! The recommended amount of overlap to use is 1/4".
• Don't go crazy. There is definitely such a thing as too much exhaust insulation. Over-insulating exhaust parts is the primary cause of parts fatigue and early failure! There are probably over 100 different types of exhaust wrap, many promising better insulation at an increased price. But you don't want better insulation; you want exactly the amount of insulation that this product offers. If you use excessive overlap, double-wrap, or use overly aggressive exhaust wrap, you'll be much more likely to have problems. Furthermore, if you use too much exhaust wrap in the same place, it can actually prevent the metal from expanding properly, compounding the problem.
• Install dry. It's been suggested by some websites and manufacturers of exhaust wrap that you get it damp prior to installing. This makes it easier to install and gives you a better seal to hold in more heat. It's hard to say how much damage would be caused by this one-time moisture, but it probably doesn't help. Clean and dry your exhaust parts before installing, and install the product dry to get a good head start on rust prevention.
• Keep dry. The main reason exhaust wrap can cause premature rust is because it holds moisture. If you're cleaning your engine bay, go ahead and put a plastic bag over your wrapped headers - the cleaning supplies won't do much to clean the exhaust wrap anyways. If you happen to drive through a lake by mistake, consider removing the header wrap, drying, and re-installing. If you drive through a lake on purpose and regularly, using header wrap probably isn't the best idea... unless your components are stainless steel.

Important:

• Note: it is normal for exhaust wrap to smoke and smell funny for a couple hours after installation.
