bought these for my silverado about 4 years ago. have some surface rust on them but they work great. i upgraded to long tubes so i dont need these. they have the EGR tube but no AIR injection. asking 150 shipped. i am still waiting on the long tubes to get here so it might be about a week before i get them off.

 

make offer bump? maybe im asking too much.

 

Do these bolt tight onto the y tube?

 

yes you dont have to modify anything.
