A factory produces a certain product, with a factory price of 50 yuan per item and a cost of 25 yuan. During the production process, an average of 0.5 cubic meters of wastewater is discharged for every product made. To purify the environment, the factory designs two plans for wastewater treatment and prepares to implement them.  
Plan 1: The factory first purifies the wastewater before discharging it, using 2 yuan of materials for every cubic meter of wastewater treated, and the monthly wear and tear cost of the wastewater treatment equipment is 30,000 yuan;  
Plan 2: The factory discharges the wastewater to a sewage treatment plant, paying a fee of 14 yuan for every cubic meter treated.  
Question: (1) Assuming the factory produces $x$ products per month and the monthly profit is $y$ yuan, find the relationship between $y$ and $x$ for both wastewater treatment plans. (Profit = Total Revenue - Total Expenses)  
(2) When the factory produces 6000 products per month, which wastewater treatment plan can save expenses and yield more profit for the factory?
