Supreme SP Honda Civic Si Coupe 12-15
Part #: 10158209
The Supreme SP for the 9th-generation (FB) Civic Si features our signature GReddy layout, styling and sound, with a newly revised piping diameter. It is designed to be compatible with both Si models; coupe and sedan (using the optional 11050108 adapter). The straight-through resonator and specially-made oval muffler with offset extended tip allows the system to follow the Civic’s body lines and help reduce drone and high pitch frequencies. It also provides good power gains throughout the usable power band.
