TECH TIP: MINI Cooper S (R56)
Performance Exhaust by Sound Speed
Overview:
The MINI Cooper S performance exhaust system by Sound Speed is a direct replacement to the factory exhaust system with upgraded tubing diameter and muffler design resulting in more horsepower to the wheels.
The system is constructed of 100% 304 stainless steel, and it is made with 63.5mm diameter tubing which is about 10mm more than the MINI Cooper S factory exhaust tubing. The longer stainless steel resonator removes some of the drone sound from the engine, and the rear muffler is fully welded, not crimped seams making it more desirable for performance applications. This Sound Speed exhaust system is hand-made in Italy, and designed specifically for the MINI Cooper S R56. (Read more info about each individual component below.)

The Sound Speed turbo down pipe is 304 stainless steel with mandrel bent tubing. Each pipe is 65mm diameter giving a very low back pressure which enables turbo spool up for high horsepower & torque gains. Installing a complete performance exhaust system achieve +26 hp with +20 lb/fts of torque.
In place of the factory quad cat design, soundspeed uses high volume and flow 200 cell count metallic race cats. These are placed further away from the engine for the lowest restriction and the best results. Fits models:

Sound Speed alternative Center pipes with resonator replace the metallic race catalytic converters. After the turbo down pipe flange, the diameter down-sizes from 65mm to 60mm. This is still larger than the factory 57mm diameter. This diameter is this size all the way to the tail tips.
Our Center Pipes are mandrel bent for maximum flow and performance, and are manufactured from 100% 304 stainless steel. There are no crushed places in the tubing like the factory exhaust pipe. Fits models:

The Sound Speed rear performance mufflers are a resonated flow through design, rather than the factory baffled chamber design. The internal tubing size creates performance while the internal wool provides the best possible sound deadening. Fits models:
