ETS Subaru '22+ WRX Axleback System

This axleback replaces the VB WRX's rear exhaust sections while retaining the factory-style two-bolt midpipe connections. I'd choose it when the main goal is more exhaust sound and a different tip finish with a simpler installation than a full catback.

Extreme removes the mufflers for greater volume; Muffled is easier to live with on a street car. Uses 2½-inch stainless piping and quad 3½-inch tips, with gaskets included. The factory center exhaust remains in place.
