i just installed my dual exuast , flows, but i wanna drop my car to lower the gap, but the problem is it already rubs on speed bumps i have to drive really slow, want can i do to avoid this , and drop it ? ANY ADVICE

 

Where does it rub on speed bumps? on your aftermarket exhaust? on the frame of the car?

If your shocks are replaced at the same time, even though you lower it, it may prevent any kind of rubbing over speed bumps. If your shocks are bad, it will allow your suspension to quickly compress and rub.
