Exhaust Manifolds

[Mark One]

As far as i am aware, the 10bhp power difference between a 172 and a 182 is down to a remap but mostly due to the exhaust system.

This is why when i try and buy 182 manifolds they are all around the £250 (cit-ren on ebay) mark as a 172 manifold can be had for £50-60.

Also the 182 4>2>1 manifold doesent bolt straight onto the 172, but Ktec do custom sports cats and also a Decat is fairly easy to fab to solve this TBH.

SO SURELY - there is a gap in the market for someone to be doing free flowing, bolt on manifolds for 172 owners. If they could do it for £200 or £180 they'd make a MINT.

Does anyone know anyone already doing this or is anyone thinking of havin a crack themelves?

do you have any idea how hard it is to make a manifold as complex as the 182 one! £250 is a bargain!!!

 

[Mark One]

......yeah.....they look pretty hard. Given

 

[Fred@BTM]

one of the pipes is hydroformed, that costs a fortune

 

[Fred@BTM]

£402.32 + vat new from renault (trade get a 10% discount on that)

I wounldn't have thought hydro forming costs that much on an industrial scale.

I think the time to weld all the pipes together would be the most time consuming and expensive. The 182 mani is made up of like 20 different pices, must have cost reno a fortune to make.

 

[Mark One]

Perhaps I'm just annoyed cos they are the most expensive french manifolds on ebay. I WANT ONE CHEAP!

 

[Diesel_Power]

Cost Renault nothing, cost us a fortune.

 

[Fred@BTM]

13 pieces to be precise!

what i meant was that replicating "the bendy pipe" (in 1 piece) nearest the gearbox would be impossible to do without spending a fortune on tooling etc

 

[Fred@BTM]

well if you think a plastic splitter is £130+vat

and a work of art manifold is "only" £400+vat (a V6 plastic side pod costs more than that!)

well if you think a plastic splitter is £130+vat

and a work of art manifold is "only" £400+vat (a V6 plastic side pod costs more than that!)

but then again V6s are rare and the production volume extremely low, so that is going to bump the cost up.
Thousands of 182s were made

me and my mate Gray who picked a manifold was already thinking about it. Gray's dad works for magnex and they have hydraforming gear to do it. however after looking into it it works out very expensive for the first few as custom jigs need to be made
however saying that im gonna pester him into finding out exatly how much it woulld cost and then if enough people show an intrest maybe this could be an option however dont count on it as they tend not to do manifolds in general unless its for a superbike in which case micron does most which is the same company!!

 

[Fred@BTM]

2000 sidepods made, £500 a go

thats £1million!!!!! for plastic!!!

 

[Clioman51]

yet the splitter remains stupidly expensive!!!!! some body really has to make a cheap version thats very very slightly different so its not copying!!!!!!!

 

[Fred@BTM]

i could knock them up no bother (in fibreglass) but they'd have to be painted (either matt black or colour code it etc)

i'll look into

 

[Clioman51]

i'll have one hopefully it will be cheap!!! matt black all the way too!!!

 

[Fred@BTM]

it won't be textured like the original, it'll be smooth

 

[Clioman51]

that wont bother me!!!

 

[Gray]

it won't be textured like the original, it'll be smooth

mmm smoooooooth...

Even better!

 

[Fred@BTM]

i'll look into it tomorrow!

we were gonna ask BTB about making 182 manifolds.

But decided in the end they would be pretty expensive, plus people are put off by the labour costs of having one fitted (if they cant do it themselves).

i think your best bet is to pay £250 on ebay for one!
