100% stainless steel "TWIN PIPE DESIGN" system, Oversize 1 x Ø80mm –› 2 x Ø54mm –› 1 x Ø76mm
The valve, which is precision-machined and built in house at our facility in Mantova, Italy, is designed to be operated by the same Audi factory servomotor used on the stock exhaust.
No modification is required for the installation.
Put the SS rear muffler on the car, connect the servomotor onto its mounting provisions, and go. That's it.
While this new rear muffler guarantees an extended range of sound options, the core parts for making the real power gains are still the Supersprint turbo downpipe, and the HJS Motorsport, high flowing catalytic converters.
As always, we have several setups available, each for a distinct, intended use.
The 70mm, single-line system is sized to handle tuning modifications, to the upper limit of 320-340 Hp, while the unique, larger diameter Twin pipe system is the perfect setup for more radical tunes, up to 380-400 Hp.
The Audi S1, with a full Supersprint exhaust and the right engine modification program, has the potential to become a quicker accelerating, faster car than Audi's own S3 or VW Golf 7R.
