I was just wondering if I need a dual muffler and exhaust tips, The crossover pipe looks a little rusty but enough to hold. I don't know if I need a catalytic converter could not find it. But if you can tell me what you think it be helpful

Also my windshield seems to have some type of weird crack in it. It's not from the outside or inside the car but more in the middle of the Glass itself. Wondering if it will still pass inspection.

Here is the Windshield


Driver side crossover pipe


Passenger side crossover pipe


Crossover pipe going to front of car


Please let me know what I should do, I know my muffler is my next task and money will be tight next month, so if I can just put dual mufflers and exhaust tips with some clamps that be awesome
