Supersprint exhaust system

[Pisobiker]

Thanks to Rafael (The_Spanish) who asked me about Supersprint systems, I discovered that this very well known Italian Company builds a good looking 70mm turbo back SS system for S2 and RS2 (I didn't know they did for our cars).
Don't know the price, Rafael was going to find out.

here is the site:

SuperSprint


Apart from the exhaust itself, what I found interesting is the rolling road charts they show for the S2 (which, looking expecially at the torque values, I guess is a ABY):

Original:

239 hp @ 6350 rpm
353.5 Nm @ 2820 rpm

With Supersprint exhaust (turbo back 70mm)

250 hp @ 5760
403.5 Nm @ 2590 rpm


following is the graph:

note that test was done in 3th gear for sure (end of test speed ~165 Km/h @ redline) and total mechanical drag (but of course not the aerodynamical one) is ~50-55 KW = ~ 70-75 hp.

Found this very interesting so I wanted to share

They seem to list them as for the Sedan and Avant but not the Coupe? AFAIK the sedan and avant have the same exhauts but the coupe is different after the cats.

The first S2 I ever drove was a '94 Avant with a full Supersprint turbo-back system with a hi-flow cat. The owner claimed that it was a custom job by Supersprint, since they didn't list any system for the S2 back then. Maybe they used his car to design the system Marco referred to?

If I remember correctly he said it was 80 mm, but don't know if it was just the downpipe. I didn't have a very close look at the exhaust, but it seemed to be well built. It was perhaps a bit on the loud side, making highway driving a bit tiring, but all in all a very impressive system. However at the prices we're talking about, it should be...

764021 (pipe kit with cat) + 764003 (centre exhaust) + 764006 (rear exhaust) = list price approx. 3350 eur from a dealer here in Finland. Phew...

PS. Don't know if they supply full turbo-back systems for the S2, but one interesting exhaust option is bn-pipes.

:eek2: seems a little too expensive to me, even for a very well done and high performance system.
Fortunatly for me I built my own 3" SS turbo back system spending much less than that.

I will have a price for the 70mm downpipe with cat 764021 by tomorrow because the spanish distributor doesn't list any car previous to an A3 in their catologue
The downpipe is the only usuable part on the Coupe, the rest must be a custom job but I find the downpipe would be the most difficult part to customize, the rest I am thinking would be a straight 70mm pipe into a 70mm modified milltek exhaust muffler.

Cheers,

Rafael

P.S. 70mm aprox. 2.76 inches

[The Spanish]

Just looked at the BN pipes web page and they do have a 70mm pipe back box with twin 2x76mm exits so one less thing to adapt.

Just receive a call while writing this post, the price I have been given for a 70mm downpipe with a metallic cat is 1149 Euros discount and VAT included. A tad on the expensive side I think.

Cheers,
Rafael

I found the price for the non-cat downpipe - 564 euros (about £400!!) which is a tad steep for a simple tube.

I can make that for less then halve the money

I`m currently busy with making my own exhaust system out of SS. And also i`m making my own high flow mufflers out of SS. I`m doing this together with Jeffer, done some prepperation today. Made some perforated 3" tubes out of perforated SS plates.

The whole system is gonna be 3"

But €5xx is ****** lot of money for a downpipe, those people who sell it will laugh there asses off

I happen to have a 2 and 1/4 supersprint system. They made this setup for the 20v 7a motor.


With RS2 setup will this be to restrictive? or will I be ok?

THanks

[Pisobiker]

Josh, I don't remember exactly diameter of OEM S2 single pipe, but I'm afraid 2-1/4 is in the "small" range of dimensions.
Take also into account that NA engines tend to have smaller diameter ducts to maximize pressure pulses energy, while forced induction engines and turbocharged ones particularly need a high flow exhaust to maximize turbine efficiency.


Marco

[Josh-stateside]

I figure that was the case.

I will just have to sell it to someone here in the states.
Custom 2-1/2 or 3inch Seemingly will be have to be made.

Thanks
Josh

[Pisobiker]

Josh, just take into account Supersprint does a 2-3/4 system for the stock RS2 so if I was you, having to build a custom one, I would definitly go to 3", allowing for some higher hp outputs if needed in the future.

I've been doing some digging on the supersprint systems as i'm after a 2.75" system.

Ideally i'd like to get my hands on an RS2 downpipe (hello Bry!!!!!!!!!!!!!) but if not the supersprint downpipe is available for £226.87 without Cat (would then get a sports cat put in)

I think thats not a bad price for a downpipe?

[Rusty]

Am I correct in thinking that the Rs2 DP is a direct replacement but 2.75" rather than 2.5"?

[s2driveruk]

i'd like to remove my dual 3b cats and replace with just a single hi-flow sports cat - any recommendations.....? Car is the wrong side of the cat issue on MOT and I can't be ar*ed to replace each year.

Cheers
