stock exhaust manifolds....yea you shouldn't have any problem with smogging.

 

Call them and ask.

 

Your stock cats are already hi-flo, so unless they are crapping out on you, I wouldn't spend $$$ on new ones.

 

mornin everybody i appreciate the imput ! and hi Jenna bear ,the little ole 4.8 is runnin good ,real good thanks to you and Justin ! still can't thank both of you enough for all your help in this project.can't wait till the new pulley comes in.and the kats are 2.5 in. wanna go bigger for the flow.Thanks Jim.

 

Glad to hear you are enjoying the extra ponies, Justin did mention that you were going with a smaller pulley

Honestly, I would stick with your stock cats for now, and put that money towards LT headers.
