It's 2,5" - 2,5" but the main part is larger

It's WRC Rally and Rally Cross cat. HJS Motorsport. The one that Dahlback sells for 600 EUR each.

I can't find the paper where the specs are so using the meter and my precise eye :

lenght: 28cm
in,out diametr 5,7cm
main body diametr around 11cm.

Quite heavy. For a 3" just cut some adges.

Price 250$.

"Engine Performance Output
The approval of the T¬¾V Bayern for the catalytic converter concept and further tests have shown that HJS high performance catalytic converters do not produce any loss of engine performance (measurements according to DIN 70020) and keep within the exhaust gas regulations. "

" The use of metal supports with 100 cells per inch©÷ (cpsi) and the excellent construction of the cones with regard to the flow have the advantage that the exhaust back pressure is not increased, avoiding a reduction of the engine performance. The optimum supports guarantee long duration of life. The intermediate layer (wash-coat) is resistant to high temperatures and guarantees the high stability that is necessary motorsports.

YHM,

change of plan I want it when ever you have time to make it.

Sweeper this is the answer I got from HJS

quote:

"Dear Mr. Rafael,
thanks for your inquiry from today.
The catalysts you have mentioned are not the right one for street cars. The motorsport catalysts for street car have to run longer distances than race cars, therefore we recommend using the catalyst 90951546, if you prefer a catalyst with flanges or 90950015 without flanges.
With the obove mentiones catalysts you will have no problems with the emissionstest."

Then when I looked in the catalogue for the new part numbers they are DTC (Touring Car homologation) and ar good for up to 2000 cm3.
So new part number is for a under 2 litre engine touring car that is not even turbo so

The Spanish: Hmmm , Hans from DahlBack said it's ok and they install them to s2/rs2 cars.

But I bought 2 , but I bought 2 exhaust systems aswell.

[The Spanish]

Sweeper,
I know what you mean. WRC exhaust should be the ideal for S2 as they have similar size engines and outputs (on RS2 modified form). However this is a new response I got.

quote:
"Dear Rafael, the catalyst I have recommend to use are absolute the right one for your car, we have tested them in cars with more than 350 HP with very good results. The homologation says nothing about the maximum power for it.

The different between the WRC and the cats I Have mentioned is the length; you need the length to have the security for the emission test.

I don't know what to believe.
Does somebody know if this is true or if their stock on the touring car CAT is to big?

Rafael

[The Spanish]

I just remember I am a good friend of the manager of RalliArt Spain.

Does anybody think the CAT for the Lancer EVO (or their GR.N) or even (WRC) is a possible choice?

Engine is a 4 Cilinder 2 litre single turbo with around 310 bhp on stock form and a lot of potencial to improve.

I am sure I can get a very nice deal on it.

Cheers,
Rafael

Rafael, any metallic cat converter good for 300 Hp on a racing engine I think would be more than enaugh for a 360/380 Hp high performance street engine.
Of course an even freer flow cat converter could give anoter couple of Hp on top, but I don't think this would be the real deal, and then emissions rules might also not being met.
As I told you my cat converter was rated for "only" 280Hp application and it's working quite well on my actual setup.....

[The Spanish]

Je, je Ralliart work with HJS CATS
So I must ask the same person for info on the CATS.
At least I can get the one he suggested me with a nice discount

Sweeper, they do sell your CAT and they told me your price is very good. But they also said is a Group A CAT and for them is also too small to past MOT tests.
I am still not sure though.

How much bigger is than the the standard Downpipe??

Have sorted out my money situation and am now on the hunt for more power...

Am looking to get an RS2 EM and turbo prob same as Greg's as was v impressed when i've been out in that.

I assume your DP would be worth fitting on to this setup???

Plus means single pipe and no split and at that price!!!!
