Hey guys I have this wierd noise that comes from under the car when it rains. The mods i have are tbe, hks rs, evc v, and thats it. When it rains and im driving down the road all of a sudden I get this clunk clunk clunk noise. again this is only when it rains. I feel it where the shifter is and i have to completely stop the car and pick back up from where i left off. I dont know what it is. So any help would be much a appreciated.

Thanks

 

your downpipe is hitting the subframe.
I have a Helix 3" DP (old version) and this happens whenever it gets wet. Not sure how. My fix was to put a piece of silicon hose aroudn the pipe where it hits the subframe. And help it there with some hose clamps.

 

I had the same problem with the cat back part of my Turbo back . It truns out that when the underside of the car would get wet the exhaust would hit the driveshaft carrier bearing . I rigged a pice of hose with to clamps to stop the rattle .

 

sweet guys thanks for the help. It drives me nuts cuz i think my car is falling apart. if any others have this problem and its not what the other two posted please chim in.
