S2forum request for Wagner RS2 Downpipe

[macspring]

Given the posts on here, it might be worth doing the same good work for B4 S2 ?

Not sure of one into two as per ABY and / or a 3 inch Dp where one repalces one's exhaust at the same time.

Say what about the 3 inch exhaust also?

Above are long shots, but would be worth looking into ?

Others may have comments or opinions ?

NCTS BTW, but good quality, easy bolt on, is very appealing.

Thanks and kind regards.

2nd vote from me - A properly good 76mm stainless downpipe for ABY that deletes the Y-pipe (and has optional sport CAT) would be fantastic - with two bungs up top and one bung down low...

[madpugger]

As Paul says, 76mm, optional sport cat, two bungs up top and one down low and a flexi would be helpful too!

Also, very nice work there as usual Carsten

custom is the only way.

engine mounts, turbo configs. etc.
we must have been through this enough times to realise a generic 3" wont work.

wagner kits is great but even the old tubular to new tubular which is designed to have the same turbo mounting position needs the downpipe or centre modding. the downpipe ends up being an inch short.

what turbo would it fit to? its a total waste fitting to a k24.

if you want one why not just run it to a fabricator and have it made so it fits properly. too many variables otherwise and buy the rest of the great kit from carsten.

When I say 'generic' - I mean for K24 and RS2 applications - on 3B, ABY, B3 or B4 - I don't mean generic for all turbo and manifold options - that is impossible. I realise there isn't a massive amount of clearance down there, but if someone like Carsten can get it right then it should be a nicely priced option from a trusted source - better than ten of us going to ten different local 'experts' and getting varied results IMHO.

Actually if Carsten was making it, would make sense to work with his EM - but that should dimensionally same as RS2 in terms of where main pipe and WG pipe would bolt up to ?
The above statement is not so true if non original WG is used I suppose - easy to see how the desirable goal of something nice and generic gets complicated.

i think it may be worth it on RS2 to make the 360-380hp range but not on 3b aby for 320hp wringing it to death. save the cash for a decent upgrade.

as a package upgrade for RS2 that may be worth it. manifold, dopwpipie to upgrade RS2. hope your mounts are as good or bad as the fabrication subject or i reckon there may be trouble ahead.

generic downpipes will help generic maps too eh paul

I think potentially this should be taken onto a different thread as it has gone a bit off topic from his RS4 downpipe announcement in the Wagner forum space.

[GazzaG60]

your right jamo. sorry carsten. forums and tangents

[Jamo]

I've moved it to here, be easier to track between the two, it should be doable only hurdle would be finding out when Lupo911 gets his RS2 back!

[Sonic]

Id be very interested in a wagner 3" downpipe + sport cats.

If it could bolt onto the milltek cat-back even better.

Soon its going to be "Powered by Wagner" rather than Porsche! Wagner intercooler, xmember, inlet manifold, exhaust manifold, downpipe, cats...

Thanks Jamo, nice move. Quite right too.

Gazza, I agree with your points, but the spec mentioned in Paul' s post # 2 is what I had in mind.

Wagner may decide to to offer a 3 inch down-pipe, but to be able to use it easily, one would have to make sure a couple of items are in place first;

Fresh standard engine mounts with an 034 front engine mount snubber, a single sports cat or single by pass pipe, doing away with the ABY style of one into two split. A Wagner RS2 Evo exhaust manifold.

The turbos it could initially be made for would be the Garrett GT2871RS or the GT3071 would would be the right size of turbo to match a 3 inch down-pipe, and RS2 exhaust mainfold on a road car.

By having these items in place, it would lessen the potential fitment issues that might occur.

If one wants a bigger turbo or to drag race the car, such owners would presumably be looking at a custom down-pipe anyway, but for the rest of us who want to be able to bolt up a 3 inch downpie with spanners rather than a welder to our road cars, Wager may might consider the possibilities ?

Custom is all very well, but a lot of the time I would have thought that peoples hopes for decent 3 inch DP are not met by their local exhaust companies.

Not sure if there are other variables that have to be taken into account that would complicate my simplistic view of the possibility of a Wager 3 inch down-pipe becoming a reality.

Please feel free to put me straight. Every day is a school day for me.

Kind regards.

Some good points there.

I agree that a 3" DP for a car with standard mounts, RS2 EVO EM and 3071 would be the best combo because a 3" with standard S2 or RS2 turbo would not bring the same benefits.

I don't think it would make too much difference having the EVO EM or RS2 OE one as far as the exhaust goes as there is only 5mm difference in turbo placement between the two.

[GazzaG60]

as a set kit maybe itll work. still id expect some issues on soem cars.

aside from my preference to custom i think that 3 bungs are needed. i have 2 Wb02 and 1 egt. be aware that egt bung may need to be smaller and it may also depend on your probe type.

i can understand the issues as there are some really poor jobs done and people get upset quite rightly. ive seen some bird **** city welding in my time.

only other thing to consider is does carsten have a rhd car to fab one from or is everything the same down ther lhd or rhd.

Hi All

I'm in the middle of changing from an OEM manifold to a wagner evo and am interested where the 5mm difference is in dimension is as with a 3071 there may not be 5mm to play with as its a bit on the tight side on mine already, Actually had to move engine over 5mm when on standard manifold

I've got a custom 3" downpipe made by a local company which I've added a flexi and believe me there's not much room for that. If I was doing it again I'd spec a turbo and DP with a V band as it makes life soooooooo much easier

[madpugger]

The EVO manifold is the same as OE except the Turbo is 5mm closer to the engine. This was done exactly for the reason you have just mentioned about the turbo being close to the chassis leg.
