Just to clarify (confuse?) further, I bought my '92 new. I still use the
original pipe from right after the original crossover and it is 3". The cat
inlet & outlet are both 3" and the pipe to the muffler was 3" except for
where it necked down to about 2 3/4" right at the muffler inlet. I don't
remember for sure the size of the tailpipe. It's all 3" now. :)
