So i drive a 98 ex coupe with a stock d16y8 (only with an aftermarket air intake) with 85,600 miles. I do drive the car fairly quickly most of the time, but rarely redline it or abuse it. Also, it only has 85k on it. I dont think any civics should be making these noises with so few miles...

Here's the scoop. The other day, I was driving, and hit a bump. Not huge, car didnt bottom out or anything, but just a little bump while i was accelerating up a hill. As soon as i hit the bump, it sounded like I had an exhaust leak. The muffler almost sounded like it had a hole in it or something along those lines. I didnt worry about it.

But today, I was driving home from a mariners game (beat the rays 9-6!!) and my car was making the most god awful noises ever. No CEL, no nothing. Only the wretched sound.

Here are the links to the videos, one from the interior, and one looking under the hood.

My cousin has a 96 sedan that makes the same noise, but hers is a total POS, and I just want to make sure nothing serious is going on under my hood. Any help is greatly appreciated!

It sounds like the rattle is coming from right under the firewall....
When the car was purchased, it had an aftermarket exhaust. If im not mistaken, the aftermarket piping was left on the car with a stock muffler put on. other than that, the engine has never been tinkered with.

How's your oil pan? I'm hearing a little rattle, especially in that second video.

When was the last time your car had a tune up?
Is it possible to go under your car when its cold and maybe give the exhaust a little shake? Sometimes heatshidels come loose, or bolts break.
You may also need a valve adjustment

Definitely.

I had spun a bearing... so on top of needing a whole new bottom end, I also needed a new tranny, new trailing arm bushings, new timing belt, head gasket, and camshaft seals.

$3,200 later, and my car is running like a dream again lol

DAM! There's no emoticon for a minor heart attack so, this will have to do-
