Metal clanging? Check the heat shields. I had mine removed because there was always a banging sound at a certain RPM.

Could be the cross-bar halfway down the exhaust hitting the exhaust pipes? Although I'm not sure why it would suddenly decide to do this. I removed mine on my sedan. lol

Would it be a hassle to remove them? Also are there any disadvantages if I remove the heat shields?

So i removed the heat shields by my test pipes today and it cleared out most of the metal rattling noise. There is still a tiny bit but I think thats the nature of test pipes. Thanks everyone for the advices!
