RS2 Exhaust - Supersprint cat back

[simon44]

I'm going the Supersprint cat back route. One of our friends in Italy has given me great insight into this as he has been running this set up for 3 years, says that there is a little more sound below 3,000, its a comfortable noise when cruising, and sounds great above 6k. And a dyno test suggested an increase of 9 BHP, which is icing on the cake. I'll let you know how this goes. Steve at supersprintuk.com has been really helpful and quick to respond via email.

When it's time I'll be buying supersprint...and maybe in that time some excellent choices in the aftermarket will arise to challenge that choice. Would be cool if they did a 3'' downpipe though

[simon44]

I've been looking around on their .com site and they suggest that the high flow rates they achieve deliver the benefits without increasing pipe diameter. As I am not intending to go for modifications to the standard set up/turbo etc I think this should be good for me but understand what you're saying though. Maybe longer term the buying power of this forum and enthusiasts alike will lead to something closer to what you are looking for.

Good luck with your search.

Simon - I think that explanation is called 'marketing'... But every ounce of knowledge and common sense in my head says the bigger the pipe, the lesser the restriction to flow.

For my modest needs a 70mm stainless is probably enough but the cost of the Supersprint is mad - though its quality is NOT in question. Maybe I'll have to buy the 70mm downpipe and get a stainless system made that works to that.

Maybe your mate at Supersprint can be cajoled into some S2 Forum discount - maybe if we secure an order of 5 or 10 downpipes - just another idea to keep options open.

I figure a 76mm downpipe is just better suited to RS2 and bigger turbos that can really see the benefit of further reductions in back pressure. Its a real shame we have to go for a full custom build on that.

Hello, what do you think about BN-Pipes exhaust system included downpipe, sport cat, etc for the RS2? Probably I will try it on my RS2 very soon. Thanks a lot!

Never heard of them before - but interesting options there for Audi...

Thats a 70mm downpipe for 695 Euro - and their systems for B3 and B4 are over 1300 Euros - I rest my case !

Hi all

I reckon that Simon choice it's good for my experience.
Also the price for the kit in pounds it's not far from what we have here in Italy
(well the pound currency it's confusing me in the last period though...)

About downpipes in 70mm from Supersprint or complete system in 70mm.....

Supersprint it's a small company i have been there myself to fit my kit and the owner himself did the roll on the dyno for my RS2.

Because the company it's not so big it might be that we have the chance to ask for what Peter says.
My connections inside Supersprint are good enough to try and make an enquiry and see if it's a big deal for them....
Of course everything will then workout throug the UK importer eventually.

I'm not into metal work (i'm a marble man...) but afaik it's all down to "templates" isn't?
S diametere should'nt be such a big issue....

Opinions?

Hi Paul, I tried the bulk buy on the forum idea but at the moment because of the Euro there is very little margin so I am not sure that they will go for this. I have suggested that they join the forum so maybe something will come from this further down the line. We're doing all the exhaust/manifold gaskets on my car at the moment so I'm sort of following the rust and chaos further back to the corroded centre box and rattly rear silencer. It's a lot of money I know but I've just been paid by one of our clients so I'm going for it before the money gets spent on something else like towels or garden plants!!! The exhaust will take a couple of weeks to arrive but I'll let you know what its like once its fitted.

Cheers

Stefano thanks for those prices you offered a while back. More info you receive from Supersprint in regards to a larger downpipe would prompt me to order a kit for my Coupe right away. And if a group buy do come to fruition even better...

[madpugger]

I bought my supersprint full system for avant with de-catted downpipe for around £850. The dealer gave me 30% discount so if anyone is interested I can give them a call to check the trade discount is still the same.

I suspect Supersprint may well make a 3" DP if we gave an order. AFAIK they stopped manufacturing the S2/RS2 system a good few years ago then decided to re manufacture it. When they did this i believe they updated it too.

I was thinking of supersprint downpipe, Jetex backbox and custom middle section.
Thought I could add a cat later for mots.
Reckon it will cost me about 700quid

[S2central.net]

Problem with Supersprint downpipe is that there are two - one with a sports CAT integrated. One without... You'd need to cut the decatted downpipe to accomodate a sports CAT being fitted later - again not something you'd have to worry about on a proper modular system.

Question on the Jetex box - I forgot about that one - is it stainless or mild steel ?

[sjw185]

Jetex is 2.75 st/st backbox seen it for just over 200 quid. forum member Add has a couple of good photos
Was thinking about cutting the straght downpipe later and fitting a cat in with vbands
and using the cut piece for a bypass pipe.

cheers

Paul, please contact me about 3" Downpipe SS.

EDIT:
WTF!
I was probably on some kind of high

Yeah that is true, I am going to have to fit my cat again next month However I am sure Supersprint would make a DP the way we want it, ie with bolt in cat or de-cat section if they were to make us a 3" one.
