Exhoust which size to RS2 setup?

[Jonas_R]

Well,

I'am looking in to getting a 2.75" SS exhoust system from Downpipe to my rear silencer. However i were not planing to mount a front silencer is this stupid?

My setup is RS2 ic, injectors, EM, turbo and hopefully a mihnea map
Well my aim is around 340 hp and perhaps 500 nm.

On downpipes, iam a bit confused

Dont really know what to get perhaps rs2 one?, but will this give to much restriction compared to the 2.75" exhoust?

My plan is to change the exhoust from downpipe to rear silencer when iam going to the MOT.

[AAH!]

Standard RS2 is 2.75". You'll end up wanting more than 340hp so why not skip 2.75" on go straight to 3"(with removable cats).

Hehe no i just want more then my friend in his cosworth So no need for more power then this. But you are tell me that a RS2 downpipe is 2.75" you sure about that? Because then i'll just get a rs2 downpipe and i'll consider the 3"

Jonas you probably have to sell your turbo to me and get a RS2 one if you want 340hp

Does the RS2 downpipe fit the ABY Coupe?

Yeah but as far as i can tell by the numbers on my turbo it is a RS2 turbo. The cold side is anyways and i got the rs2 EM. This is way i want to go for a bit more power, got the turbo and em

[Jonas_R]

Yeah good question there anybody know this.?

/Jonas R.

[porkkis]

Straight fit.

[Jonas_R]

Straight fit.

Oki think i will get a RS2 downpipe then

And i dont want to sell my turbo, sorry porkis
As i mentioned before the cold side is a RS2.

Dont know about the hotside yet iam afraid.

Ok ok, I give up

Try Sweden (nordicaudi köpes/säljes) for the downpipe. They usually sell them cheap like 500 sek.

Hehe thanks for the tip, was looking to buying it from new. But can i get it used for like 500 sek then ill def. do that

But any comments (looking aside you want to buy my turbo) about it being a RS2 when hotside definately is rs2?

As you have told you have the Hohenester 310 kit it should not be full RS2 spec but smaller. AFAIK.

I'm after one of these "MTM small hybrids" or similar. Top hp is limited to around 320-330hp, but it's more responsive because of the smaller hot side.

Yeah oki i guess i will have to take a look the hotside. Can i meassure the Outside diameter on the hotside?

/Jonas R.

[porkkis]

They are all #6 cast so no, you have to measure the machined outlet inside diameter AFAIK.

Is the RS2 downpipe one 2.75" to a single cat or does it split into 2 and go to twin cats like S2/S4?
