Back after a long absence is the GP Moto silencer delete elbow! This is a highly recommended part for WRX's and STi's alike. The factory air intake system has been proven to be as good as or better than many aftermarket upgrades out there and with this silencer delete and an upgraded panel air filter (sold separately) you can rest assured that you are getting high performance levels out of your intake system! This elbow along with a Perrin panel filter (sold separately) were used on our WRX with VF39 turbo and we couldn't have been happier with the results. No MAF issues and a great stock look all while upping performance for a price everyone can afford!
