I have a cattman SS Ypipe on my 96. On the cattman webpage they have a different Ypipe for 95-98 and 99-01. I'm about to buy a 99 fed spec and was wondering if the Y off the 96 will fit the 99? What are the differences? What has to be done to make it work? Thanks for the input.

 

to the top, somebody has got to know.

 

Fed spec should be the same.

99-00 Cali and All 01+ have precats that are part of the manifold and have more o2 sensors.
