Sport exhaust system for Audi S1 Quattro 2.0 TFSI 231hp

We developed two different exhaust set-ups for this mode: single pipe and "Twin Pipe Design".

The single pipe system is similar to the OEM exhaust, but with larger bore components and higher quality of built and materials.
It's composed by:
-Turbo downpipe with integrated HJS high flow cat or cat-less. The catted version is recommend for up to 280-290hp. For higher output we recommend the pipe-only version (see also the twin pipe system)
ECU tuning is recommend with the cat-less DP or the 100 CPSI catalytic converter to avoid the Check Engine Light.
-Front section, with or without resonator. The un-silenced version is recommend to be fitted with the catted downpipe, the silenced version with the cat-less downpipe to get a more refined sound, especially for people who doesn't want a noticeable sound increase.
-Centre section, with or without resonator. The un-silenced version is recommended for the catback (centre+back) setup. The silenced version for the full system, especially for the cat-less DP and un-silenced front pipe.
-Rear muffler, free flow design without chambers. No valves, for a sportier, deeper and rounder sound at all revs.
-Tailpipes: we recommend the ovals 100x75, which fill the arches nicely, basically an upgraded version of the stock items.

The "Twin Pipe Design" has been designed to get the best of the performance without sacrificing pollutant emissions reduction.
The S1 frame doesn't allow to fit a sports cat under the car, in the transmission tunnel, in the proper size for the reachable output (130mm or more), so the solution we found is to split the exhaust line into two and use two high flow HJS metallic cats, smaller but with a total cross section adequate to an output of 300 hp or more, even adapt to upgrated turbo applications (S3 8V turbo for example), without gas flow restrictions.
A collateral advantage of the twin pipes is that they cause less resonance and drone compared to a single pipe of equivalent section (76mm).
Because of the structural differences of this system compared to the OEM ones, it must be fitted as a kit from turbo to tips.
We recommend the centre silencers for an optimal comfort onboard.
