I have a pair of 6 liter exhaust manifolds off of my 03 Silverado SS. These are the same type of manifolds that people are using to make turbo kits and W2W powered their own car into the 6s. These also have NO EGR provisions which some of the 6 liter manifolds do have. Will sell for $125 PLUS shipping.

 

do you have the cat pipes?

 

No I only have for sale what it pictured.
