all of a sudden, my exhaust is noticeably a lot louder than before and i hear a lot of rattling where the pipe is. i checked under my 95 hatch and i saw some loose screws where the exhaust and the piping meets. after tightening it up, it's still loud. when i say loud, i mean LOUD! it sounds like a monster when im going at 10mph! i don't know what's wrong with it! i notice when i start up the car, i can feel air coming out between the piping and the exhaust, and the air is not flowing to my stock exhaust. is something wrong with my car?? please help! btw, is there some sort of piece that is suppose to go inside?? i think it's called a doughnut, or o-ring.

 

yeah, you probablyly have to replace the doughnut, they fall apart after a while and the two pipes dont seal.

 

You have an exhaust leak, probably from a broken or missing gasket (or doughnut) where the pipe connects.

 

i have a 2 inch piping.. do you know where i can get one?

 

just go to an exhaust shop or an auto parts store might even have them.
