The end all of 2008+ WRX Sedan Exhaust is here! It was designed with the smooth lines of the new chassis. The result is a clean look adding a level of sophistication but while offering the sound that does not sway far from the boxers World Rally heritage. In true Turbo XS fashion it is made from T304 Stainless Steel, 3 inch piping diameter all the way out to a mirror polished 3.5 slash cut tip. The addition of 6-10 whp in Catback form makes it a great bang for buck. If used with the TXS Downpipe and Catpipe you are looking at a minimum of 30whp gain.
