Hello all,

Had Pacemaker headers installed on my vehicle for a few days now, just wanted to know if anyone had ever installed this wrap to their headers? Are their any bad experiences out there with wrapping of headers (in particular Pacemakers)

Thank you all

Greetings All.

Same question...is it worth while??

Cheers,

Good idea, should be done prior to installation.Not necessary if HPC coated, but if done may have problems with cracking of welds and even the metal because of the heat being held in.All depends on quality of metal and weld etc.,

haha, yeah, do it before you install the pacemakers. haha, but I wrapped it when it was on the car, I only had enough to do the front, but the effects are reduced engine bay temp slightly. No idea whether it helps in terms of power. When I get my next set of pacemakers if I brake my current one, I'll make sure I'll wrap it good.

I know it guys, I honeslty did not think about the wrap till after the gear was installed. Now you fellows talk a lot about breaking headers and things of that nature, is this a common problem? Is it due to clearance issues or what?

Well, if you drive hard enough around mountainous twisties, you're bound to scratch something sooner or later, and with lowered springs it doesn't help, the front of my pacemakers sit about 130mm off the ground right at the front primaries, so if I drive very fast into a ditch, I can hit the extractors on the rising side of the ditch.

Awesome! Not that theres a chance in hell the cars getting raised to compensate but, hey?

what about wrapping ur standard extractors, i got 4-2-1 extractors on my TP and when i put my pod on, i noticed how hot the actual pod gets due to the extractor heat, would it help if i wrapped the extractors and put a cold air intake system onto the pod?

if your POD is getting so much radiated heat from the extractors, then yeah, wrapping them will help you heaps. That's if the heat is actually coming from there.

yeah the heat is coming from there, the way the intake is designed the pod sits about 2 foot from the extractors, i was thinking maybe a heat shield but id rather do it properly ie remove manifold, wrap it, install a CAI system and then she will b sweet

Magnamayhem, if you're going to go through the trouble of taking off the manifold to wrap them then why not going all the way and replacing the headers. The biggest pain in the rear for me throughout this whole project was that because the US version of our cars has so many different emmissions restrictions, nobody would take on the work. I ended up doing the installation myself.

Removing the manifolds was the biggest hassle, once you have them off putting the gear back on is quick. I should have wrapped the stuff before installing but I did not think of it. Like you I have a pod in my engine bay,, i have it shielded a bit but still wrapping I think will eliminate a portion of the heat being created and going into the compartment.

The other advantage apart from reducing engine bay heat is that the exhaust gasses reach the cat hotter than what they would have done otherwise, resulting in cleaner emissions from your cars rear end, and longer cat life :)

if u put a pod on you should really have a heat sheild. u are aware that if u get pulled over and they pop the bonnet and see the pod exposed u can get booked for defecive vehicle. if u have a pod they are supposed to be fully boxed in. the best thing to do, if u have a newer model with a factory cai is to take the piece off at the front under the mouth of it that surrounds the bonnet latch. this lets cold air from the nose grills come up into the cai . then just put a k&n panel filter in. a na car doesn't need that much air flowing into it. if it has a hairdryer bolted on then use a pod.
using the factory airbox with a proper cai will give you more power than just a pod because the air being forced in is cooler, and at a higher speed it is being forced in at a slightly higher pressure. a pod in a cold air box works even better because more air can be forced in. if u want to go further u can get heat sheilding that works great. cost about $150 per square meter, but this will keep the air cooler.

moral of the story, have cai, and have it sealed so no hot air from under the hood gets in there.

Most of the people in the know that I've talked to are against the idea of exhaust wrapping.

It won't happen straight away but the increased temperature can cause crystalisation and welds can break etc etc.

Better off just getting them HPC coated or leaving them as is.

^^^What billy said. The exhaust wrap means the extractors are going to run at higher temps, the end result being shortened header life, so there is a few longevity issues to consider. The way Ive always looked at it is that heat wrap is a cheap alternative to HPC coating. If your after heat wrap, I say do it properly and get HPC coating, other wise dont bother, although you have to remember the gains arent going to be huge so you have to ask yourself if its going to really be worth it.
