Corsa system and water
This has been problem from the beginning with my Corsa system, and I know others had the same horrible vibration when driving through lots of water. Did anyone ever solve this problem? Corsa people seem surprised and clueless.
Not that I am aware of. It only happened a couple times with me. Do you have headers or cats? It seemed to go away once I became more modded.

when I had mine installed before the Kooks were put on I ran thru some heavy heavy rain the same day and it bogged down big time and thought it was sucking water thru the Roto Fab but all was dry.
It happened a few more times then nothing again. Not sure why I even talked to Corsa and they were not sure why it was casuing but he did say it might be the cats cooled down to fast.
One of those mysteries of life

I thought back in the day some found that water was getting into the mufflers? Maybe see if you can figure out if that is happening to you?

It seems the Corsa system wants to naturally sit about 1/8" above the tunnel brace. If you don't put some type of a spacer in there before you tighten down the connection pipes (stock Corsa or Kooks), the mid pipe vibrates against the tunnel brace creating an awful noise. I went through this and it seemed to only do it when cold and would go away as it warmed up. Maybe the water is cooling it down... check the clearances here...

Thanks to all for the answers. The car definitely does bog when this happens. I'll look at the suggestions and take care of the clearance and muffler-hole issues if there.
Followup: there were no weep holes in the front OR rear cans. There are now :-) Exhaust clears BMR tunnel brace by a lot. We'll see what happens if it ever rains here again!
Wow they should have at least one weep hole in each
