Aftermarket 4 branch manifold on 172?

[seb172]

I'm currently on the hunt for another 172. I went to see an 02 plate one today and noticed that the exhaust note was a little raspy for standard. When I asked the dealer about it he told me it had a brand new standard system on it, but it had a 4 branch manifold, hence the deeper tone. I've never heard of anyone to do anything than fit a 182 manifold to a 172 before so I'm a bit confused. Has anyone else done this to theirs or heard of anyone who has?

Nobody makes an after market manifold (as far as I am aware)... they are standard 4 branch

 

[A18XHO]

they all have a 4 branch lol depends what setup. 172's come 4-1 182s are 4-2-1

dealer is talking out his arse. Could well be a fresh exhaust, could also be a decat (tend to rasp a touch). Have a look underneath

 

[seb172]

Hmm, thats exactly what I thought. I'm confused then, it's definately an exhaust sound, not induction kit as it does it on idle. Could anything else be responsible for adding the little extra noise to it? Sounds quite good but just want to know what's been done to it, lol

 

[seb172]

I'm hoping it's not a decat, I can't be arsed with emission issues at MOT time. Will have to have a look underneath tomorrow then

my 172 has a stainless manifold on it an the bore on each branch is bigger than standard for sure, i can get sum pics up 2 moro?

 

[Fred@BTM]

no one has ever made one other than renault OE

 

[172Ben]

The OE one looks pretty good in standard for to me.

 

[MarcoB]

Sounds like it blowing, like mine. Decieving when its blowing so close to engine but when you get the heat shield off it sounds beasty!

il get some pics of mind tomorrow in daylight an post em up...

 

[jono172sport]

it looks like this actually... http://www.k-tecracing.com/show_product.asp?id=1617 is it possible for this manifold to fit a 172?

 

[172Ben]

Yes with this

Dent in the 182 manifold is caused by slack engine mounts and the ARB. It's common

 

[Fred@BTM]

dent is actually factory standard, they did that on purpose!

although on rare occasions i have seen them without "the dent"

what is the better one to have the 182 manifold or the 4 into 1 off the 172

 

[Gez08]

4-2-1 low-mid range, 4-1 for top end power. However you never hear of anyone with a 182 changing to a 4-1 manifold do u but many 172 owners change to a 4-2-1 manifold. Ive read about this debate before and ppl defend the 4-1 manifold like crazy but like i say y dont 182 owners swap 2 a 4-1 if its that good?

I assume it's down to the name of the car, 182 and 172. People with a 182 might feel like they are making the car slower if they switch to engine parts from a car with less power

I thought that the 172 (4-1) manifold provided better torque and better low mid range and the 182 (4-2-1) provided more high end power....

No other way wround

 

[Nick172Cup]

Oh right. Cheers for that then, i'll be reconsidering getting a 182 manifold then! Always thought it was the other way...

 

[Fred@BTM]

pointless IMO sticking a 182 mani on

Thats what they say, depending on which threads you read lol - I found the 182 gave better top end. Just felt a lot better overall than the 4-1.

Happy with my torque level from the 182 mani anyway, would the 172 be even better?....who knows

Dont agree with it being pointless as long as its been done for about the 300 mark fitted, or less. Worth it for the ease of exhaust fiddling alone

 

[sammyhale22]

There obviously is a benefit from fitting the 4-2-1 because out of the factory the 182 is producing more power allegedly than the 172 and the only differences I'm aware of on the 182 engine are the Exhaust manifold and a different ECU map... So someone fitting a 182 4-2-1 with a henk RS Tuner remap would make gains over the 4-1.
