Skunk2 76mm Alpha Series Downpipe for 16-21 Civic 1.5T

Skunk2 Racing 76mm Alpha Series Downpipe for 2016-2021 Honda Civic Si/Sport (1.5T)

If you want your L15B7 to breathe like it should, this is the simple answer. The Skunk2 Racing Civic downpipe in the Alpha Series gives you a true 76mm pipe, that is a real 3 inch Civic downpipe Skunk2 setup from end to end, so you stop choking the turbo right after the outlet. We run these exact parts on our own cars because flow and fitment matter more than hype, especially once you add a tune.

This Honda Civic 1.5T downpipe uses 304 stainless tubing and flanges, plus a stainless flex section to help keep things sealed when the engine moves around. Skunk2 keeps the O2 sensor bungs in the factory locations, which makes install less of a fight and keeps wiring happy. You can choose Straight or Catted. The catted version uses a Max Flow 100 cell platinum palladium catalyst, so you keep a cat in the system without turning the pipe into a restriction.

Key Features:

• True 3 inch, 76mm Civic Si downpipe diameter with 304 stainless tubing and flanges

• Stainless flex pipe to help prevent leaks from vibration and movement

• Universal flange that mates factory exhaust to many 3 inch systems

• OEM heat shield compatible

• O2 bungs in factory locations, straightforward install

• Max Flow 100 cell catalyst on the Catted option

• Hardware included

• Skunk2 Alpha badge, if you care what people see on the lift

Real talk on trade offs. The Straight option gives you the most flow, but it is for race use only and it will not play nice with emissions rules. The Catted option helps, but it still may not be legal where you live. Either way, plan on a tune if you want the most from your Skunk2 downpipe Civic 1.5T setup and to keep the car happy.
