Description

The new Aprilia RSV4 and Tuono V4 2021-2022 are clearly a benchmark in their category. The racing attitude of these bikes founds the perfect match with the SC1-R muffler, the top of SC-Project products range in terms of performance and technical solutions.

Developed during many years of close relationships between the Aprilia Racing and SC-Project Race departments, the SC1-R silencer is the maximum expression of power, quality and hi-tech solutions for the hypersport 1.100cc engines made in Noale. Thanks to the presence of an exclusive valve-system in Titanium – developed by SC-Project for MotoGP and WSBK exhausts – this silencer comes in short configuration, only 250mm length for a very aggressive and sporty look.

Despite the compact dimension of the muffler which allows a huge weight reduction of -59% if compared to the original exhaust, this masterpiece of technology allows the noise level to be accepted for race track use: 105 dB @ 6500 rpm with dB-killer installed / 109 dB @ 6500 rpm w-out dB-killer installed.

For race use, the dB-killer is removable: the exit pipe obtained by hydroforming process and the Carbon Fiber end cap with rhomboidal and asymmetric shape, makes the SC1-R the best slip-on muffler for this bike. For this application the lightweight outer body is available in two options: Titanium or Carbon Fiber.

The weldings manufactured with T.I.G. technology in a protected environment, the sound-absorbing material resistant to very high temperatures and the insert bushings made in CNC machining, embellish the SC1-R muffler. The valve system is compatible with the original control unit and wiring, and this makes a plug-and-play installation. It is not necessary any ECU remapping. The kit includes a specific Carbon Fiber heat cover and the racing bracket to remove passenger footpeg, together with the mentioned valve exhaust in Titanium – derived from MotoGP factory teams – and a full Titanium link pipe.

Finally the impressive maximum gain of torque: +6,5 Nm @ 7700 rpm and a consistent increase of power (+7,2 hp @ 7700 rpm) with the baffle installed. W-out the baffle the maximum torque gain is +8,0 Nm @ 8000 rpm while the power gain is +9,1 hp @8000 rpm. Anyway the benefit is distributed and usable all around the range from 3.000 until 13.000 rpm.

The final output of this exhaust is not just sound, but it is a real deep and sensational racing music for Aprilia lovers and owners.
