The Agency Power offers a refreshing exhaust option for Scion tC owners. This is a full catback exhaust system, not simply a muffler or axle-back as most other tC exhaust are. This system features 2.25" mandrel bent piping constructed from TIG welded high grade 304 stainless steel. To eliminate low RPM drone, Agency Power has designed a tuned resonator chamber to keep you under the radar when cruising. The system is completed with a light weight muffler and four inch exhaust tip for a unique and striking look unmatched by the competition. A silencer is included.
