2017 Honda Civic sport 1.5t Exhaust

[Duneguy69]

sup guys! so i got a muffler delete like 2 months ago and now im looking into a Greddy supreme sp catback exhaust system, but i was wondering how it works with upgrading headers, adding a downpipe, and adding the Greddy catback exhaust system. can i put all 3? or could i only do certain systems?

The turbo does not have what we call “headers”. It is called as “downpipe” coming from the turbo then to a “frontpipe” leading to the resonator.

Downpipe (catless > catted), bigger front pipe, bigger exhaust.
