I have lowered my car with TEIN SS.

Recently I have been hearing metal crushing noise whenever my ride go over any kind of bumpy ride. Dealer told me it's the aftermarket suspension problem.

Does anyone has that kind of problem as well? appreciate for help!

 

like the crushing of a soda can or just rattles and what not?

because if it's the former, then i would say you need to disassemble your stuff and get it checked out. who did your install? a properly installed aftermarket suspension shouldn't make noises like that.

SSTS

 

I think it’s your muffler pipe touching something. After I got my tl it started doing that because my brother ran over a cone or something and it small mettle peace was touching the muffler pipe. Every time I go over a bump the muffler moves and it makes that noise. You can do it with pliers or with your hand makesure car is not hot.

 

Jack the car up and look. Your headers are probably scratched up, or worse, dented. how much did you drop the car?
