doing a dek swap, and came across enough money to do the exhaust while i'm at it. i wanted to make sure i don't have any problems when i put everything back together. im doing the y-pipe back. warpspeed metallic CAT, and a greddy SP2. Here is my question... For the y-pipe will i have to get the find a 5th-gen one or can I use the DE exhaust manifolds, and get a 4th gen pipe???

 

If it were me, i would pony up a few more bills for cattman headers and run stock exhaust till i could upgrade it later.

 

You will need to use the de front manifold and you can use a 4th gen y pipe
