Overview

These Milltek Sport downpipes replace the factory downpipe on the 2023-2027 Honda Civic Type R (FL5) with the 2.0 liter K20C turbo engine. Each one is a large-bore 3.0 inch (76.2 mm) downpipe in T304L stainless steel that bolts to the turbo and the factory mounting points.

There are four versions. The catless downpipe has no catalytic converter at all. The three catted downpipes keep one: a cast downpipe with a 200-cell race cat, a downpipe with a 200-cell HJS high-flow cat, and a twin-cat downpipe with two 200-cell HJS cats, which Milltek calls its no check engine light version. Milltek classes all four as race products, so check your local rules before road use, and plan on an ECU remap to get the most from them.

Milltek also makes a cat-back exhaust for the Civic Type R FL5 if you want to replace the rest of the system.

How to Choose

Catless gives the most flow and is for off-road and track use only. Catted Race 200-Cell keeps a race cat in a cast downpipe. Catted HJS 200-Cell uses an HJS high-flow sports cat. Catted HJS Twin 200-Cell uses two HJS cats and is the version Milltek built to avoid a check engine light.
