it quietens the exhaust tone a bit, a set screw (allen head type) holds it in place. on my last 3 evo's i have took the thing out in the dealers car park before setting off 
stupid question!
i`m sorry if this is a stupid question but just need to clarify something before collecting my mr 320.i have done a search on this forum in relation to the "baffle" that is found inside a new vehicles exhaust,i am aware that this can easily be removed with just a screw driver but my question is when??? it seems that some say remove it when you pick the car up and others say it should remain in place for at least the first 100 miles or even leave in it place all the time.what is its purpose and what is to be gained by removing it??? sorry,but answers would be appreciated
