Hi guys
What's the significance of the insert inside the end of this tailpipe? (IMG:http://www.914world.com/bbs2/uploads/post-222-1372820267.jpg) I see it a lot on big vintage 911 engines too. Is it there as a noise control solution, breaking up the sound wave in some way? or is there something else going on? |
