2018 Honda Civic Si – Downpipe, Exhaust, & Tune

Rodney brought in his 2018 Honda Civic Si to get the FC1 chassis tightened up, and the turbocharged L15B7 engine turned up! Up first, Archer installed Eibach Pro-Kit lowering springs along with front & rear swap bars (29mm front & 19mm rear), and then wrapping up the mechanical work with an aFe POWER down-pipe and 3.00″ catalytic-converter back exhaust system. With the mechanical work wrapped, up next Vlad is dialing it all in on the dyno via Hondata FlashPro.
