Exhaust wrap...

[r8byb]

Benefits of wrapping exhaust, thinking of doing de-cat, centre section and upto backbox..

I'm aware this keeps the gases hotter, being hotter it flows quicker as it's denser..

Any downside's to doing this ?

Cheers Rob

heard it makes you itch like fook lol

also heard that water can get in under the wrap and when it heats up and cools down can cause the manifold to crack

only heard mind

 

[geesus69]

yes it is very itchy!

it will need re-doing as the wrap deteriorates over time (think mine has lasted well over a year though!)

have you looked into ceramic coating? more expensive than wrapping but much better results

Flows quicker because its less dense.

It'll cost you loads to wrap the whole system and for bugger all result in reality.

Cost me about 90 to wrap a 182 mani. Clips alone are about a fiver each or something daft

Just transfers the heat to another place, i.e. your backbox so eventually will blow it pieces.

Just use chicken wire Thats what i used on my tubular manifold. About £2 for a roll. Much tighter grip than those rubbish clips aswell.

Im tempted to wrap mine aswell. dont know much about the benefits of a faster flowing exhaust compared to a turbo car which im more used to

Pimpest thing to do is getting the manifold ceramic coated...

^^
Yes

Cold air dense / hot air not dense

More used in turbo projects too i think.. ^^ Andyman found out it's no use

 

[Andyman]

I reckon to do the whole exhaust you'd be talking upwards of £300 and for what gain in the real world? non

Buy a Maxogen instead haha

 

[r8byb]

£300, im wrapping my exhaust not my whole car

 

[Fred@BTM]

its expensive stuff! and it's 100% pointless doing the exhaust and not the manifold

took me 6hours to wrap a 182 exhaust manifold (off the car) and was over £100 in wrap

 

[172Ben]

£300! Where the hell do you buy your wrap from!

Cost me less than£100 all in to do manifold, and full exhaust system including two rear exit pipes.

90 quid did a 182 mani. Full system is a fair old distance like. Obviously your 1'' ebay sh1te will be cheaper

Save your dosh fella. Non of the bigger boys are doing this lark

 

[iimushroomzii]

Bearing in mind it cost about 80 - 100 quid to wrap a mani I would say it wouldnt be far off 300 for full exhaust. Totally not worth it IMO

 

[172Ben]

i bought thermo tec

 

[RichCup]

Ceramic or nothing IMO. Heat wrap gets wet and holds moisture and will reduce the life of the exhaust.

 

[Andyman]

^^I dont buy that.

Exhausts get hot, moisture would soon burn off and in anycase, if your heat wrapping its gonna be on a stainless exhaust, not stock, with stainless welds perhaps? which dont rust

 

[mattjk]

I was told the whole moisture gets inside it and rots the exhaust is tosh.

^ Ive been told that too
