L98 Y-Pipe Question
What is the size of the 350 TPI Y-Pipe on 1-Cat cars? If you knew that would save me the jacking of the car.
Also, I am looking to buy stock 350 TPI exhaust manifolds if anyone has any they would like to get rid of.

The pipe going into the cat is 2.75". I believe the down-pipes are just over 2".
Check the classifieds for stock manifolds. They're the same as '86-'90 305 TPI as well.
