HAI ok, so... after taking aboard all the pros and cons of doing it, i'm going to heat wrap my extractors to try to reduce under bonnet temps and possibly loose a few hidden killerwasps... i've got 30m of the stuff as well as a whole bunch of steel cable ties... now i'm after suggestions on how to actually fit the stuff... i mean, obviously you just wrap it around the pipes, DUH... but i've heard mention of soaking it in water first, and spraying it with exhaust paint after, and wearing gloves cos it's made of fibreglass and stuff like that... anyone have any pointers before i jump right in and do it this weekend?? anyone want to give me a hand??

Hai, rusty manifolds ahoy!

I hear it's best to fit it using your teeth...

thanks for your constructive comments guys

I've wrapped my dumps, didn't bother with gloves. No, I cannot help. Just make sure its really tight the whole way down, if you see it loosen off you'll have to unwrap it back to that point and just start again from there. Its time consuming if your doing it by yourself, so if you have an extra pair of hands its always very helpful.

Tristans manifolds are 6" off the ground and Mild steel. Can no one else see the issues surrounding wrapping them in an absorbant material that retains heat as its main goal in life?

[cracka]

oh yeah, your gonna fu*k your mild steel manifolds by the way hehe

I sense large amounts of failure

one side is done... i took pix but can't get imageshack to work at work... all i can say it FARK!! fibreglass is itchy!

[cracka]

mate ask your mechanic if it's a good idea to put that stuff on mild steel extractors cause i've seen some nasty things happen to mild steel from heat wrapping .

[CRUISN]

Tristan will find out soon enough. Ive also been told mild steel is a no no to wrap. I didnt think there were much gains to be had from wrapping NA headers?

[Soop]

Pitting from heat. Rust from trapped dirt and water. Been there done that, got the post card. I told him this about a month ago... There is gains if your racing. The heat wont build up under the bonnet, which means the engine runs better for longer. 140kw street car, it makes no difference. On a 140kw H6 with the manifolds hanging under the car it makes even less difference to performance.

ok, so I'm going to listen to you guys (and the 11ty billion other people on the webz) and unwrap my extractors...

*waits for the "i told you so"s*

what a waste of $80...

anyone want to buy some exhaust wrap?

[Soop]

Deadset. This is just stupid now.

[Scuba-Roo]

didnt think they'd rust up THAT quick? what made you change your mind?

[Soop]

No, they would/do. Particularly being on the coast. The salt in the atmosphere will get trapped in the wrap. Pefect reciepy for munted steel.

what made you change your mind?

that i don't have a spare $700 to replace the extractors if it does actually f**k them up

it's an expensive chance to take...

what's so rediculous about it soop?? i'm actually taking your advice now...
