Exhaust Header Wrap Guide

We get a lot of questions around what exhaust wrap to buy, how much of it and various other questions. No problem, they’re all good questions, so we figured it’s best to put all our questions down in one place with the answers. We’ll update this page as the questions come in, so feel free to send us any others to contact@levelxms.com.

Why should I wrap my headers or pipes?

Take it straight from the experts at DEI. Here’s what they say: Wrapping any type of exhaust piping is a crucial and important step when controlling exhaust temperatures and reducing radiant under-hood heat by up to 50%. Keeping exhaust gases hotter within the exhaust system helps in decreasing density and increasing the flow of exhaust gases. This improves exhaust scavenging which, in turn, reduces intake temperatures for increased horsepower gains.

Also, limiting the radiant heat trapped inside the engine bay decreases air intake temperatures for a cooler air charge, heat absorption through the fire wall which keeps dash components and cabin temperatures to a an absolute minimum. PLUS it has a cool carbon fiber look!

How much exhaust wrap do I need?

This varies a lot depending on your application. Use our handy calculator to figure it out!

How much exhaust header wrap do I need for a V-8?

A typical wrap of V-8 exhaust headers requires either 2x 50′ or a single 100′ roll.

How much exhaust wrap do I need for long tube headers?

Lots! Based on our experience, you need about 60′ of 1″ wrap per side. Alternatively, some folks have used two rolls of 35′ or 33′ of 2″ wrap instead. Don’t take our word for it though. Either buy extra or just use our calculator.

How much exhaust wrap do I need for a motorcycle?

It’s best to use the calculator to get a more detailed estimate, but based on our experience, it’s best to get a 50″ roll. Don’t forget to buy locking ties as well if your buying separately or just get an exhaust wrap kit instead.

Can I use hose clamps on my exhaust wrap instead of locking ties?

This is not recommended. While it may seem like a great idea, hose clamps have a tendency to loosen up over time and may also cut into your exhaust wrap, thus damaging it.

My locking ties appear a little loose around the wrapped exhaust pipe. Is that an issue?

No problem. This can happen and they will work just fine.

What’s the benefit of titanium wrap over regular wrap?

The major difference is that it does not need to be wetted to install. It is much more flexible than standard exhaust wrap and thus easier to install.

How do I decide to use 1″ or 2″ wrap?

For tighter bends, it’s recommended to use 1″ wrap to get around them smoothly vs. 2″ wrap.

Do I need to cure my pipes in an oven after wrapping them?

No, simply start the engine. No matter which exhaust wrap you choose, it will smoke when you start the engine while the wrap burnishes. Titanium wrap smokes very little compared to the fiberglass based wraps. Either way, you will want to be in a well ventilated area while this occurs.

What is Titanium exhaust wrap made of?

Titanium exhaust wrap is made from pulverized lava rock, stranded into fiber material then woven into a tight weave. Titanium exhaust wrap is able to handle more heat than typical glass fiber material.

 

What is the recommended overlap when wrapping?

Overlapping 1⁄4″ is recommended, because this keeps the maximum heat in the exhaust while allowing enough out. You do always want to let a little bit of heat out, since otherwise you run the risk of overheating your exhaust and depending on the material, it could degrade over time.

How do I secure exhaust wrap to the header?

You should use locking ties. It’s by far the easiest and least prone to slipping. Hose clamps will work, but are not recommended because they can easily loosen and slip.

Nissan L28 Individual Throttle Body Kit

Here are the parts to put a Jenvey Dynamics ITB setup on your L28 engine:

Alternatively, you can also go with 90mm long throttle bodies instead of 118mm. These are:

VW Squareback ITB Kit

The Volkswagen Squareback is an iconic little car. With this rear engine and “frunk”, it’s pretty darn unique. People are also doing some pretty unique builds of them. Here’s a parts list if you want to put and ITB (individual throttle body) kit into yours.

You of course will need a few more electronics to make this EFI setup run, but this is the basic air/fuel plumbing.
