P_G that's on the same dyno?

Is there a chart on the same dynamometer of a standard RS4?
As we haven't tested one that goes over 375 bhp yet.

Not sure about how much do you think to gain with just catback and remap...I think you'll be around 380 bhp, maybe 390...
If you want some real gain you should think about sports cat or decat.

About valved exhaust, they fail pretty often, especially in poor weather conditions.

D'OH! I thought I was answering on the S4 exhaust thread!! The headers are still under development, we'll try another primaries diameter before starting production, we think there's still room for improvement, especially on the top range of revs. I can't tell you when, it would be pointless. Prices ...

Yes I work at Supersprint. Where do you live? I can't tell you the exact price and availability, but probably December. I suggest to ask to your local dealer and place an order, for a new product we start the production when there's a sufficient number of orders, usually there are no problems with A...

The sound is very different live...the HD camera and the microphone I used for the S4 video (see the thread in the other section) arrived a few days later, so I had to do it with what I have (a SD Sony camera with the standard, poor mic...the instruments shoot is taken with a Nokia phone!!) The soun...

Here is the video of an RS4 with the complete exhaust. No cat, 4 into 1 headers (prototype still under development) and cat back. I think it sounds nice! The car has a custom remap and a filter. http://www.youtube.com/watch?v=_OWszr_1SQA What do you think? Power is around 420hp (it had less than 370...

Just finished the video...All the info on the website, prices still not available. http://www.supersprint.com/USP000auda491.asp http://www.supersprint.com/public/images/34145.jpg http://www.supersprint.com/public/images/34158.jpg Video (turn the res. at 720p, full screen and pump the volume!) ttp://...

The 458 is flat crank too...

yes we are sonny! Probably i'm going to do a full fluidodynamic study on them in the next months. A few photos!
