2017-on Honda Civic Si Coupe (only)
The unique dual muffler Supreme SP for the 10th generation Honda (FC3) Civic Si coupe features high-flow with a refined exhaust note. Under wide-open-throttle, spirited driving, the system offers the classic GReddy deep exhaust growl. To enhance the performance of the turbocharged 1.5L engine, this 3piece, cat-back exhaust connects to the factory piping (our system bolts to the factory exhaust system at the flange behind the engine/transmission) and expands to large 3” (76mm) forward-midpipe and mid-pipe that split to two polished, straight-through SP oval mufflers and dual center-exit dual-wall GReddy tips. This tip and muffler combination is a great compliment to the Si’s sporty, but wide rear bumper tip opening. (We also offer a similar, application-specific system for the (FC1) Civic Si sedan.)
