Hi guys,

So the rain was was crazy today in South Florida and I drove through the puddle, not that deep I think, at a speed of about 20 mph. Immediately after that the exhaust started to rattle veeeeeery loud. I pulled onto the parking lot right away and I even found a spot that was pretty steep upward hoping that maybe that water got inside the pipes and somehow and it would come out after reving it up few times but no luck. The car did not stall, the check engine light on did not come on so I decided to go home right away. The noise inside was so bad that I could not shift higher than 1,500 rpms, after that 8 mile ride my ears were even hurting. You could even feel the vibrations inside. So after I got home I let it sit for 3 hours and started it up. The noise and vibrations did not go away. My abs + tcs + slip lights came on, my rev display started going crazy up and down up to 1,300 and even went down to 0 when the car was on. The engine got cold after sitting for 3 hrs and I saw temperature going up normally and then suddenly this gauge went to 0 as well. The check engine light did not come on again which I thought was a little weird maybe. At this time I just shut the car off.

I went through some bigger puddles a month ago during previous storm and the exhaust rattled a little and went away after couple of days but this is totally out of control. The puddle wasn't that big but I guess the speed was higher than last time because I didn't see puddle coming. I've read in some other posts that one guy got lucky after leaving his car untouched for 3 days and it started working normally again...

I will check the oil tomorrow and cold air filter. I don't know whether to start the car again or wait extra day... How could I remove the water from the exhaust pipes or even check if it is there? I might be wrong, maybe the headers and test pipes rattle so loud...

I have test pipes and cold air intake.

Any opinions and suggestions will be greatly appreciated ! Thank you !

 

You'll have to go under and look at the headers and test pipes. It's possible that they could have cracked. The test pipes run very hot while driving, and the splash of cold water on them could have made them crack, especially with cheaper headers/test pipes
