I recently had a custom catback exhaust put on my 96 ex. It has been about a month now and when I am in reverse I hear a shaking or rattling sound. I think it is my exhaust bolts in need of a tighen. What do you think?

And how do I post pics?

 

get under the car check that all the hangers are on there good.....if they are, shake it, and ull be able to tell if a bolt is loose.....on a side not, i had a rear end rattle as well (stock exhaust)....it turned out to be some sort of resoivor or ABS related thing (im guessing) was nocking against something....so check to see if anything is knocking back there.....does it sound like metal hitting metal?

 

I would say definately the hooks

..but maybe check the muffler bearings too

 

I have the same problem, but I think mine is related to the filter on my intake. I'm still trying to figure out what it could be.

 

Well when you put it in gear is probably does it in drive too (but since after you put it in gear you mash tha gas j/k ) you just dont notice it too much. You may want to check your cat and the bolts for that. My friend had all kinds of problems with his civic, but fixed it fast with just a through pipe (loud as fawk). Or you can also check your header bolts to your cat, over time they may start to rattle themselves off.
