Full Race Catback Exhaust Adapter for 8th Gen 06-11 Civic Si

Full-Race 8th Gen Honda Civic Si Catback Exhaust Adapter

If you run a Full-Race catback and you like to change parts as your build evolves, you already know the annoying part. One header swap turns into a whole exhaust redo. This Full Race Civic Si exhaust adapter fixes that. It lets you keep your Full-Race catback exhaust adapter in place and swap headers or downpipes without buying another catback. We use this exact idea on our own cars because nobody wants to cut up a perfectly good system just to try a different header.

This 8th Gen Civic Si catback adapter fits 2006 to 2011 Civic Si Coupe FG and Sedan FA. Pick the flange size that matches your current header or downpipe. The 2.5-inch Civic Si exhaust adapter option works with the OEM header and some aftermarket headers. If you step up to a larger header or downpipe, grab the 3.0-inch Civic Si exhaust adapter. Both options aim at the same thing, keep the joint aligned and sealed so you do not chase leaks or fight fitment under the car. If you want a Civic Si exhaust adapter that keeps Honda Civic Si catback compatibility intact after a header change, this is the clean way to do it.

Bottom line, this Full-Race Civic Si performance adapter is the simple part that keeps your exhaust plan flexible. It is basically your Civic Si exhaust header adapter and your Civic Si header change adapter rolled into one, and it saves you from redoing the whole catback every time you change direction.
