AWE Touring Edition Exhaust for 2017-2020 Honda Civic Si FC1/FC3, Dual Diamond Black Tips

The 10th-generation Honda Civic Si brought a turbocharged 1.5-liter engine and a six-speed manual, but the factory exhaust keeps it quiet. The AWE Touring Edition Exhaust for the 2017-2020 Civic Si sedan (FC1) and coupe (FC3) gives the L15 a fuller, sportier voice while staying civilized when you just want to commute.

Every AWE Civic Si edition includes an integrated front pipe, so the system replaces everything from the factory downpipe back. The Touring Edition adds a rear muffler with AWE's patented drone-canceling 180 Technology®, tuned specifically for the L15, to cancel the frequencies that cause cabin drone at highway speeds without muting the car when you rev it. AWE quotes maximum gains of 6 hp and 1 lb-ft of torque at the wheels.

The dual layout uses a stamped stainless Y-merge to feed two 4.5-inch double-walled slash-cut tips, a clean, purposeful look that sits neatly in the Si's center outlet. Diamond Black is a deep gloss black that suits darker cars and blacked-out trim. AWE's MERGE modular tip design means you can switch between dual and triple tip layouts later with an AWE tip conversion, without replacing the whole exhaust.

AWE handcrafts the system in the USA from 3-inch CNC mandrel-bent, U.S.-sourced .065-inch wall T304L stainless steel in a clean, straight-through design. It is a direct bolt-on and is covered by AWE's Perfect Fitment guarantee, No CEL guarantee and lifetime warranty (one year on tip finishes).

Frequently Asked Questions

Does it fit both the Si sedan and coupe?
Yes. AWE builds it for the 2017-2020 Civic Si sedan (FC1) and coupe (FC3).

Can I use it with an aftermarket front pipe or downpipe?
It includes its own front pipe and bolts to the factory downpipe; aftermarket front pipes are not compatible.

Can I change from dual to triple tips later?
Yes. AWE sells Dual-to-Triple tip conversions for this exhaust.

Is it street legal?
AWE lists this system as 50 State Legal because it does not tamper with any emissions control or monitoring devices; it bolts on behind the catalytic converters. AWE does not publish a CARB Executive Order number for it, and local sound limits vary, so check the rules where you drive.
