on the very end of the exhaust system on my 4 cylinder d21 , it looks like a small round muffler , but it is after the long regular full size muffler , what is this for?
i added a magnaflow performance muffler and a tip , thinking it would sound good (sporty) not to much noise difference though , is this some type of silencer?
thanks
