Turbo Manifold with Equal length runners Audi s2 s4 rs2

[bogdanclung]

Hi,

I intend to install such an exhaust manifold, from www.customparts.com.pl/en, on a Audi B2 chassis, along with a T3 turbine precission 5858.

Someone who has installed such exhaust manifold, can tell me if they have problems with cracks or other problems?

I must say that the car is used Drifting competitions, have very rigid suspensions and I use ALS system.

Until now I used a low price stainless steel exhaust manifold, bought from ebay and I had only problems with it.

Thank's.

you will always have problem with cracks om any tubular manifoil; it the steel are 304( stainless) and 316 stainless and acidfree, it its lower than 2333 qualitet... then you does hav the 321 verson (titan)....its the best... but usual black steel( waterpipe) will do the job too, but the weight will bee heavier...

If the thickness is more than 2mm - 3mm is better, there will be no problems with cracks at all.

good bracing is your friend with tubes.

This is description from their website:
§ Fabricated from thick 2mm wall ST304L stainless steel.

§ 38MM Inside diameter for maximum overall power band.

§ TIG welding for ultimate strength and durability.

§ Machined head flange ensures perfectly sealed surfaces.

§ Design allows the use of 3.5" downpipe for maximum performance.

§ Our manifold`s collector is welded on the inside and the outside flanges.

§ Can be used up to the GT42R turbocharger.

Until now I use thermic insulation on my old manifold. I don't know if this help for cracks easy
