2007-2018 Jeep Wranglers (designated JK model by Jeep) are great vehicles and were a major leap forward for the Wrangler in terms of 4x4 capability and prowess. The Wrangler JK also marked the debut of the 4-door Wrangler, a version that was hotly debated and doubted internally as to its potential success. It would quickly prove to be the best selling model of the Wrangler ever and come to outsell the traditional 2-door Wrangler by a wide ratio.

One thing the Wrangler JK is notorious for is the amount of heat coming from the exhaust system on the driver’s side. Even with the factory carpeting in place, the amount of heat radiated upward easily penetrates the floor and heats things up to an uncomfortable level. Using FLIR technology, we document before and after results installing Heatshield Armor exhaust insulation on out subject Wrangler JK’s exhaust system to get those floor temperatures down to an acceptable/comfortable lev

Heatshield Armor Insulation Demonstration

Heatshield Armor™ exhaust insulation is the best, most effective exhaust heat reduction solution, lessening the amount of heat radiated by an exhaust header, pipe, catalytic converter, and muffler by up to 70 percent. By drastically reducing the number of heat components the exhaust system is exposed to, Armor helps to increase i

Insulating a vehicles exhaust system has multiple performance enhancing benefits, especially on turbocharged or supercharged vehicles. When it comes to performance improvements, the key factor is exhaust gas velocity (EGV) which ties into exhaust gas temperature (EGT). On the other side, insulating the exhaust system significantly reduces the amount of heat radiated by the exhaust system inside the engine compartment and underneath the vehicle. This reduces the amount of damaging heat exposure components near the exhaust system are subjected to, leading to longer component life and proper function without heat being a major factor.

Follow along as we break down the benefits of keeping more heat in your exhaust system.

Turbocharged Applications

On turbocharged applications, insulating the “hot side” of the turbocharger and keeping more heat in helps in multiple ways.

Installing High Temp Exhaust Wrap: Key Benefits

Whether it’s a street car, a race car, or a vehicle that sees a bit of both, installing a high temp exhaust wrap provides multiple benefits that increase vehicle performance while improving reliability and longevity. Any time you can control and reduce the amount of heat being radiated from your exhaust system–from the headers all the way to the tailpipe–your car, truck, or motorcycle will be better off, and so will you.

About Exhaust Wraps

What is an Exhaust Wrap Made Of?

An exhaust wrap is made of a heat-resistant material such as fiberglass, ceramic, or titanium and is used to cover the exhaust manifold or headers of an engine. The main function of an

Why You Should NOT Use Exhaust Wrap on Your Cast Iron Exhaust Manifold

What kind of thermal barrier/insulation do you use on cast iron exhaust manifolds? It’s one of the most frequent questions we get at Heatshield Products. The majority of customers ask about if they should use or what kind of exhaust wrap to use on their vehicle’s cast iron exhaust manifolds. Our answer: do NOT use exhaust wrap on a cast iron exhaust manifold.

One more time. Do NOT use exhaust wrap on a cast iron exhaust manifold.

The main thing behind why you don’t use exhaust wrap on cast iron manifolds is the cast iron needs to breathe so it doesn’t exceed its maximum rated temperature. Similar to installing Heatshield Armor/Muffler Armor exhaust insulation, where you leave a section of pipe uncovered to allow the pip
