i would recommend high heat temperature coating instead of wrapping... but it depends if it's available in your country or not... you can get it professionally painted in New Zealand at this website below HP Coating or you can buy spary paint which is for high temperature exhausts and DIY it... it's quick and easy compare to wrapping... at works just as well too... gonna get mine painted later.... |

ceramic coating is also an option, few companies in australia do this, they do this alot to turbos and turbo manifolds i've also seen intercooler piping done too apparently works fantasic and looks good aswell theres quite a few finishes from bright chrome to matt black blues and reds |

ya it does, but you wouldnt put it on without water... if you wait til water's dried, it'll still make the smoke anyway... my suggestion for people attempting heat wrapping their header is to use hose clamps instead of steel ties, best if you could add steel wires in the combination. and don't paint it with high temp paint, wrap it wet, and wear gloves when curing the heatwrap, do it in an open space when car's stationary, or take it for a drive at night, or it'll be pretty embarrassing if you stop at a set of lights and smoke starts coming out of your bonnet... it creates public safety concerns, although there's no real risk involved Edited by chiksluvit, Sep 19 2008, 08:40 AM.

just wrap the runners dont bother with the collectors or the flex pipe, wrap won't stay on properly and will come off over time n dont paint the wrap like how some wrap companies recommend... good wraps include thermotec, DEI... some e-bay ones are good too like the one johnnyli bought b4, stay away from this brand called heatshield products, they're not woverned as tightly and fibreglass flies everywhere in the engine bay.. though it still lasted for about 2 years before it started falling apart and just use hose clamps to secure it that said i really need to get my headers rewrapped...

Hey i was wondering about this wrapping your manifold thing....if you wrap it that means it holds more heat in, so it doesn't escape as much, so your engine bay isnt that hot. Doesnt this also mean that the cat would heat up more now cause the exhaust gases are hotter? It wouldnt be that hot to cause the light in the speedo cluster to come on would it? |

nuh cat will be fine... in fact running too rich would be harsher on that cat than wrapped manifold... its good to wrap manifold, keeps engine bay temp down, prolongs the life of rubber and other things around it, cooler intake air, faster scavenging exhaust= better response.. the wrapping process was ugly though, make sure you wear gloves when you do this or your hand will be itchy for a few days... if you decide not to wear gloves, just don't go to toilet in the middle of wrapping... you can wrap it while the manifold is in the car, just harder to do and requires more patient and you'll get a sore back after.... took me a whole afternoon to rewrap the HKS racing header while its on car, but only took 30 min for us to wrap the stock headers on adriel's car...

1. should have read that before!!! 2. SHOULD HAVE READ THAT BEFORE!!! Now girlfriend is mad at meeee..... But in the end it was worth the difficulties and the painful positions, my back is still sored.... Indeed it feels a bit more responsive and smoother. But the best part is that the engine bay is way cooler and and heat vanishes faster. Highly recomended. piece of advices: a) WEAR GLOVES, otherwise youll have your hand like if you were atacked by a cat. b) Tighten the heat wrap the most you can. c) Get a massage inmediately after you finish wrapping.

i haven't had any problems iwth heat wrapped exhaust nor do i know anyone who has... from NA to turbo, track car or street car... i dont see how this can blow gaskets.. heat hardly gets passed to the flange let alone gaskets, on stainless steel extractors you see the extractors change in colour due to heat, the flange never changes colour caus it just won't heat up that much since it's thick. plus 4age 20v uses metal gasket between the extractor and the head, I think the engine will die first before that gasket will ever blow.. i understand the logic behind cracking "manifolds" but not "tubular extractors/headers"... cast manifolds can't be wrapped because the thickness of wall is very uneven, thus uneven expansion causing cracking issues. some split dump pipe for turbo cars also have cracking problem if not wraped right, mainly because the internal wastegate pipe does not heat up as much as the turbo exhaust outlet pipe, so if wrapped seperately, it'll crack due to uneven expansion. but if you wrap both of the pipes together, it won't, because it'll share the heat and the pipes will get heated up evenly but ae111 have tubular headers from factory, i'm 99% sure you're not going to have any problems.. and that 1% is for human error, like overlapping too much or not tightening the wrap etc etc..

I wraped my hks racing header with header wrap and sealed it with header wrap paint. If you just wrap it and oil gets in the wrap its easy to catch on fire. I had an autocross car of mine once leak oil on the header and it wasnt coated. It caught fire and toasted part of my harness. |

yeah gotta be careful with oil... i've heard it does burn when its mixed with wrap too but i haven't personally experienced it i did have oil dropping on my wrapped HKS headers when i change oil filter quite a few times, but that didn't burn at all.. paint or unpainted.. but yeah wrapping stock headers won't have this problem since you'd only be wrapping the top 4-2 section.. |

that depends for NA cars there's no problems wrapping the manifold, as long as they're tubular, like the AE111 ones, plus NA cars don't heat up that much anyway I've just cracked a set of equal length tubular stainless steel exhaust manifold on the R33, but they are not heat wrapped. Spoke to GCG turbo, the experts in turbo related stuff in sydney, they adv that they often see stainless steel exhaust manifold for turbo cars crack due to rapid heating and cooling, as stainless dissipates heat a lot quicker, from local brand to Japanese stuff, but cracking isn't so much of a problem on cast manifold due to the mass, it doesnt cool down and heat up as rapidly as stainless. but do not wrap cast manifolds whether its turbo or NA, the wall thickness is uneven and it will crack due to uneven expansion. so rapid heating and cooling, or uneven thickness of material (cast metal; welds on stainless) with extreme heat (like turbo manifold, they glow red when you hit boost) causing different level of expansion, also bad exhaust fitment causing stress on exhaust are the reasons that'll cause it to crack . I wouldnt really worry about NA extrators however. Edited by chiksluvit, Sep 4 2009, 10:08 AM.

i also got told it causes rust to set in even fastser on a manifold due to condensation getting trapped between the wrapping over night and stuff like that ,i have a stainless steel manifold it gives out alot of heat would i be wise to wrap it , iv already protected every thing around the manifold with reflect a cool except the rad for obvious reasons , |

the logic does make some sense if the car isn't driven much and that the manifold gets wet somehow However, usually when exhaust rusts, you'll find that it always rust more on the inside. 95% of the condensation is from there, and you'll realise you'll always have some water there when the car's cold, since exhaust gas contains water vapour. but if it's stainless, rust wouldnt be a worry, and if there was any water on the actual headers for any reason, turn ur car on and within 1 minute it'll be dried. and heat wrap isn't that great at catching moisture anyway, compared to say a cotton t-shirt. Even if it was parked in the rain, it'll be pretty much dried as soon as the roads dry up. I wouldnt worry about rust even if it was wrapped on the mild steel factory headers on the 4age 20v. Heat wrapping means less radiated heat, some gets transformed into the form of exhaust gas velocity, so quicker exhaust gas dissipation= more power, less heat so easier on rubber or plastic like engine mount or fluid such as brake fluid in your clutch line, the benefits far outweight the cons. |

used them for more than 2 years already, it's on a custom stainless steel 4-2-1 header... and it's still okay, except for the bottom parts (2nd section) it's torn abit but I've tied them with steel wires... guess would still be usable for another 2 years... I'm using Thermo-Tec 1,200... wet and dry... well i'm in Malaysia, tropical whether with plenty of rain and sun...

Ever had a look at the stock 2-1 on a blacktop? The factory piping is covered in some sort of fibre material then there is the tin covers over top. When i pulled all of this off one i had at home there was a bit of surface rust but this section was off a wreck that has been sitting at a wrecking yard so i imagine a stock manifold would be fine (so long as its not sitting round round months on end without being used) |

Im just assuming here but if its rusty with the wrapping on them. then it might just crack easier due to all the heat. but also is it surface rust or is it straight through the pipe? if its surface rust just brush it off with a tooth brush or something. then depending on the condition wrap them. |

I haven't used that stuff but what I have used is what most Repco's stock and is similar. Didn't bother putting it on wet and has lasted well.
