Description Reviews WMW Resonator Delete Pipe for 2007-2014 MINI Cooper S (R55, R56, R57, R58, R59, R60, R61). The stock turbo air discharge pipe has a plastic muffler built into it. This is designed to make it quieter, but also can offer a bit of restriction. This delete pipe replaces the plastic muffler portion only. That way you can still use the perfectly fitting stock rubber hoses and the all aluminum machined pipe can use the stock clamps and removes the restriction. WMW has found installing this will improve throttle response as the air flow will be speed up. Black anodized for long life and a stealth look.Note: Sold as individual resonator delete pipe. 3 Reviews 5 Resonator delete pipe Posted by RJ Pucci on 3rd Apr 2021 Fits perfect! 5 Resonator delete pipe Posted by Levi on 23rd Oct 2020 Well built product and perfects fit.
