What it does:
Using an exhaust header wrap or our Heatshield Armor exhaust heat shield on your exhaust system will retain more heat inside the exhaust system. This results in two significant benefits: (1) Reduces the amount of radiant heat damage to other vehicle components and lowers under hood temperatures and (2) exhaust insulation will maintain hotter exhaust gases. Hotter exhaust gases have a decreased density; this allows the exhaust gas to exit the system faster. An increased exhaust scavenging effect is produced in some cases this can also lower intake temperatures: that all equals more horsepower!
Will wrapping my pipes damage my exhausts system? No-It isn’t really a question of the wrap causing damage, it is more an issue of the quality of the exhaust system. Exhaust wraps are water resistant; they won’t keep water on your exhaust system and cause it to rust, unless your pipes become completely soaked under water, it would be very difficult for the water to get to your pipe.
Header wrap, can help to prevent rapid heat and cooling in cold climates, and reduce cracking. If the exhaust system is made from a good quality steel, insulating it should not damage your system!
All fiberglass and volcanic rock wraps are water resistant by nature, they are not water proof. The only way they could possibly retain water on the exhaust pipe, is if there were to be completely submerged in water after they were installed. Test it on a piece before installing, spray one side of some header wrap with water in a bottle, let it sit for a minute, turn it over and notice the other side is dry!
Exhaust wrap tips and tricks.
Where should you begin? Start your wrap closest to the cylinder head, work your way down the system
If you are using an exhaust wrap, avoid using a pressure washer once it has been installed. High power water can remove the coating on the wrap and cause damage to the wrap
If you wrap only a section of the exhaust system, you actually end up super heating that section of the system. The points right before and after the wrap, will actually be hotter than if you didn’t wrap that small section at all. If you can only wrap a section, be sure to continue your insulation upstream and downstream for an extra 6"-8"
By using a 1/4 inch overlap for automotive applications, and a 50% overlap for motorcycle/powersport applications, you are ensuring just enough heat to escape without over insulating the system
Heatshield Armor specific tricks:
When using Heatshield Armor, leave a 1 or 3/4 inch gap on forced induction applications at the bottom of the pipe to allow enough heat to escape system. On naturally aspirated applications, it is safe to wrap the entire pipe
In cases where you are not able to encapsulate your entire exhaust system, but you need to stop heat from radiating and protect components, use the Heatshield Armor to cover the top ½ to ¾ of the exhaust pipe. This stops heat from radiating up from the pipe, but also allows enough heat to escape so you don’t end up super heating the small section of pipe
We don’t offer silicone sprays because we aren’t in the paint manufacturing business. A good quality exhaust wrap should not need a spray to increase its lifespan. If you have to spray a “silicone” coating to make your wrap last, you need to buy a better exhaust wrap. In addition, automotive grade silicone is good for 450F tops, so advertised silicone spray for exhaust wraps will need to reapplied early and often. For cosmetic reasons, if you feel the need to spray your wrap, we would politely suggest buying some VHT or other brand ceramic exhaust paint. If applied liberally onto the wrap this should last a long time, and since it is rated for 2000F continuous, it will last longer than a “silicone” spray.
