Thermal R&D Cat-Back Exhaust Focus RS

  • Thermal R&D's innovative cat-back for the Ford Focus RS exploits the stock exhaust solenoid to provide liveable noise levels while opening up a truly snarling tone at full throttle.

    This cat-back uses no muffler at all -- there's just a couple of straight-through resonators, and a generously-sized Helmholtz resonator to dampen drone. Clever pipe routing means that when the stock exhaust solenoid opens, the system is effectively a straight-through routing.

    The result is a sound level that seems no louder than stock inside the car at idle and light load. Outside the car, bystanders will notice a slightly louder rumble. Blip the gas and there's a sharper, more crackling tone than with the stock exhaust.

    Get on the gas hard and the bypass valve opens up, unleashing a ripping, race-car note that's what we think this car should have sounded like in the first place.

    The look is nice, too. Two polished 4.5" tips cap off the system. In an interesting design detail, the tips are TIG welded right at the very outer edge, so anyone passing by can see the detailed weld work if they look closely.

    Four included slip-fit clamps allow for full adjustability so you can perfectly fit the system to your Focus RS.
