Bottomed out on a speed bump last night... should I worry?

Last night we had my car packed down with 5 passengers and two cases of beer when I made a wrong turn into a parking lot. I thought I could clear the speed bumps but the car down on it really hard and I had to have everything get out of the car so I could get over the next three bumps to exit towards the street (had I known there were three more I would've just backed up over the first one)

Anyways, I'm not even *that* low and I have koni coilovers so I figured they were stiff enough to handle the added weight without bottoming out. I knew enough to proceed over the bump very very slow but it still hit... what kind of damage did I/could I have done?

I don't have access to a lift to check everything out

How hard was the hit and where was it? Up front on the bumper or bottom of the engine or in the middle after you went over the bump. Probably didn't do much if any damage since you were going parking lot speeds(I hope) You could have hit the oil pan or bumper, bumper isn't a big deal but oil pan I would try to check. If there are no leaks it should be ok. If you hit in the middle only thing I can think of that would be at risk is the exhaust since the drive shaft is protected in a tunnel. If there are no leaks or new sounds I wouldn't worry too much.

Yea, check out the oil pan first! make sure there is no damage done to it.

actually everytime I hit , it hits these two metal mounts on the bottom that look like spots for putting the arms under on a lift.

Before I bought my S4 I had a 93 twin turbo RX7, and I could rip over these speed bumps by my apartment. So the day I bought the S4 I'm flying down this same lane like I always do and they were those rolly polly bumps not the smaller ones, and I totaly bottom the front end of the car. After parking in one spot for I while I notice an oil leak, turned out that I cracked the oil pan.

O.K. so I learn my lesson on those, but some speed bumps are just too high, and even if you go slow the car still scrapes. If you are going slow over these types of speed bumps I would imagine it's just scraping your exhaust, or under carriage, which I still have happen to me once and a while for over 5 years with no damage... that I can see.

Oil pan is fine, I hit/rubbed after I rolled over it... it probably helps that all my friends are skinny

Not even one of us weighs more than 135lbs haha

After a quick look under the car the two metal bumps on the sides of the exhaust tunnel were completely crushed and the flex pipe has a crack at the flange

I've also got a terrible creaking sound from the front suspension but I really doubt I would've hit any of the suspension components
