I'm going to be putting a new OEM muffler on my car tomorrow. I know its an easy job, and basically all you need to do is remove the two bolts that hold the old muffler to the B pipe, and then reverse the process. My question is, how hard is it to get those bolts out? I've been soaking them all day in liquid wrench. These are the original bolts on a '98 model, and the car has been in the north east for all 6 of its years. Is it going to be a bitch to get those bolts to crack? Thanks in advance.
