So after waiting a week for my new stainless magnaflow CAT, it arrived with a stray tach weld, right on the O2 sensor threads. I dont know if i'll get anything back on it, or i'll probably have to pay shipping to get an exchange.
Has anyone ran into this before? Is there a good way to clear it. I may have to rent a tap, but i dont know if that will chase it out.
