i have a old 90 cc honda and i thought it would be fun ti take out the baffle and make the people behind me go deaf... but the problem is that i cant get it out =[ there are two screws that i can see on the exhaus, one that hold it in place to the frame and one that will NOT come out...its in so good i already stripped it trying to unscrew it a while back...any help on how to remove it??  

Those screw tend to sieze up in there and become impossible to remove. Lots of WD 40 and let it soak..

After a couple days of saoking it then try some good vise grips.
