Are those things good?I sopose not to much since they cost around 100e but will they finish the job on stock s4(chiped) ?
Also i toth to make screaming pipe?Will i get any benefit using this 2 stufs?

I think the general feeling is to stay away from manifolds that are cheap ebay items.

Buy once and buy a proper manifold.

Hth

[popdemonic]

only the thing i concern on the ebay manifold is the inside of the manifold were not properly grinded off and smoothed out the surface.
let's imagine if some of that ***** missing and gets into the turbine then it's Kaboom.i'm not sure how the quality of that manifold was on this day since
i believe there're couple manufacturers replicated RS2's and Wagner's.

[Christophski]

Surely though if you purchased this, could yuo not smooth it out with a finger belt sander??? That would be ok wouldnt it? Makes it nice and smooth and gets rid of the bits that would fall off??? And of course would be an upgrade on standard S2/4 manifolds???

[Wrath]

It´s not the inside ruffness that is a problem with china manifold, it´s the material they used to make it, from all we know it could be old shopping trolleys and such...

[Majorcina]

So i shudnt get one of this?

[Wrath]

Your choice man but i wouldnt buy a china copy. A used oem RS2 or Wagner is my tip. Otherwise a black steel custom exhaust manifold is probably the best choice as they wont crack as easily as a cast one.

[Majorcina]

Ok mate i wont buy it,what u think abouth doing screaming pipe on stock downpipe and exhaust?

[Wrath]

Im not a exhaust pro but if you like noise so go for it, cant really see any benefits with it thou.

[GazzaG60]

only benfit it less gas going down the exhaust.

[GazzaG60]

if the exhaust is near its capacity limit venting the wastegate to atmosphere means that gas wont go down the exhaust.

for example a car with 2.5 inch system and wastegate vented can give the exhaust flow of a slightly bigger system.

in real terms I have been involved with one of these on a Subaru and it free'd it up at the top end of the rev range compared with routing it back into the system.

I DO NOT recommend a screamer pipe on a road car, I ran one for about 500 miles on my 3B before it drove me mad every time the car started to build boost and I like a bit of noise. You can not hold a conversation inside the car when on boost and it's a bit much for other road users like horse's etc.

[Majorcina]

Thanks for infos guys,i will drop bouth options and i will go only de cat,shud i remove the midle muffler also?i dont like to loud so i cant have normal conversation in car

[GazzaG60]

Everytime i hit boost passengers went silent. You need more boost.
Don't call um screamer for nothing

[K Simmonds]

Now I've plumbed the wastegate back in the system is 3" from the turbo back with just a back box, no cats etc and isn't as loud as I expected. You can talk without raising your voice anyway, however it does boom a bit at certain speeds.
