Hey guys,
I am wondering what the stock size of exhuast piping is on a 94 z28. I am planning on gettin hooker cat back and elimindating my cat. I was reading that hooker has 3" piping and i wasnt sure if that is what z28's had
thx rob
p.s. this is my first car i bought with my own money lol first one to mod lol

 

y-pipe 2 1/4 2 1/2 from cat-back

 

The intermediate pipe on my 95 single cat car was 2 3/4". I doubt the 94's were smaller.
