If I get ann the installation kits, how dificult is it to install the y-pipe and cat myself? or is it recomended to take the stuff to a shop? Also, Is cattman or stillen the better y-pipe? or would it be ok to go to a custom shop and have them make one for me?

 

For a Y-pipe and cat install there's no more than 10-12 bolts total. Cattman and Stillen Y-pipes are good. Good luck getting one custom made for you. Some liquid wrench and a 14 mm socket w/ an extension is all you really need for install.
