Re: So, my Magnaflow Cat-Back... (AsTrObOyo2)
Break in was over the course of about 2 weeks for me, the smell just sorta died off. It'll quiet down a little too, once the padding inside the mufflers gets broken in and expands. The black liquid is normal in small quantities, just some carbon/condensation/misc crap in your exhaust that gets burned off after the car is warmed up. I usually use a paper towel or shop rag to clean the tips, and occasionally some Meguiars metal polish for extra shine
