Nope!

 

You might consider replacing them with a higher quality set of baffles... To maintain back pressure/power....I have heard good things about these....

Honestly, if they are removable have you thought about tightening them or putting on lock washers? If they just don't fit the pipes correctly then it maybe a cobbled together system and you might be better off getting some new pipes.

 

For a cheap fix maybe pull them and wrap w/ fglass or steel wool & jam them back in?
