Wrapping downpipe-benefits
I have a nice shiny (thank you Silverscoobysport ) down pipe to fit on my classic MY99
Quick question. Is there any benefits in wrapping the top part of the down pipe
at all ?
The reason for asking is because I know said it gives you some benefits and maybe some nice noises

Not really worth it imo ....
But then lots of things we do to our cars make no noticeable difference at all ..
I did it because I had enough left over from wrapping manifold.

Downpipe not under the bonnet ? where you looking bud LOL !
And when i wrapped mine i had to use wire to secure it on as i didnt realise the S/S ties needed a special gun to secure them on, which is like £40 !!!!

the only part thats under the bonnet area is the turbo exhaust housing and about 6 inchs of pipe, the rest is under whats known as the bulkhead, now as air is going to rush under the bulkhead from the front of the car, i fail to see how it can make any difference at all, unless of course you are going backwards at some speed, as for the headers and up pipe thats another story, they do make a big difference,

Heat rises as they say, it still makes for massive heat soak in the engine bay, yes when your moving all the engine is getting cool some way or another, but its those slow poodles around 20-40 mph it helps with under bonnet temps, i like to think anyway :-)

Wrapping the exhaust manifold and up pipe is a no-brainer. But if you have a FMIC, and you retain the OEM bonnet scoop then even at modest speeds there is a considerable volume of cool air that conducts hot air from the downpipe away under the car. Wrapping the downpipe can't do any harm but whether it does any measurable good is debatable, so unless someone has done temp comparisons it's just speculation.

I've had exhaust manifolds ceramic coated. There are several places doing this, I used these:

very good product but not cheap.

I would have thought past the Turbo air needs to start cooling as it shrinks. More out! Get a blanket on the Turbo and some ducting on the downpipe!
That said a cat is more efficient red hot. Gawd.

I was always told that over lapping is better and to over overlap is better than under over lapping ( sounds all wrong that last sentence )
But good tip on the ties there
Like someone said there is a special tool for the S/S ties BTBH there was no way I was going to spend £40
And soaking them for a few hours certainly helps. Another tip is to , once wrapped, spray the wrap in a high temp coating . I have a few cans of clear high temp so will give it a quick going over to seal it

You can do the ties with pliers and screwdriver as above, we have a Band-it tool in work but you can get them just as good without it. The downpipe sits under the brake fluid reservoir too so I've always wrapped mine.
