GReddy Supreme SP Exhaust, 2017-on, Honda Civic Si 4door Sedan (only)

2017-on  Honda Civic Si 4door Sedan (only)

Designed specifically for the 10th generation (FC3) Sedan version of the Honda Civic Si, is our dual muffler Supreme SP cat-back exhaust. With similar features as our coupe version, the longer sedan version features high-flow with 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, full cat-back exhaust connects to the factory downpipe and expands to large 3" (76mm) front-pipe and mid-pipe that split to two polished, straight-through SP oval mufflers and dual center-exit dual-wall GReddy tips. The sedan version has a slight more aggressive tip angle and muffler combination is a better compliment to the Si sedan's sporty, but wide rear bumper tip opening. Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhausts carry a Limited Lifetime Warranty.
