Looking for a little help finding the correct gasket post cat on my 2005 4runner. I am replacing the existing system with a flowmaster force. I purchased a gasket form NAPA which did not fit around the catalytic but fit snug in the new pipe to the muffler. I also went to the dealer and they gave me the same one. I am not sure if this is an after market cat or they are wrong on the part. Just wondering if anyone has had a similar problem.
