Hello,
What is your opinion on Dorman exhaust manifolds for a 1999 4.8 Vortec?
I am on a budget so I cannot have headers and was thinking about the Dorman ex.manifolds from rockauto?
Do they restrict more than the original manifolds?

Thanks

You can usually pick up a set of used factory manifolds pretty cheap. You just need to figure out what set will fit your swap. You will need to do that anyway if you buy new manifolds from rockauto.

Lots of guys prefer cast stockers to headers. Generally they are less noisy, last longer and often don't dump as much heat into the engine compartment as thin tube headers. Plus they can be had for next to nothing.

^ all of that

and for those who are really picky looks wise they can be ground down and coated, depending on the car they came from they look pretty damn good

Thanks guys,
I have the stock manifolds but all the studs are broken and I don<t have drills to drill them out. Too much of a PITA for me and the tools I have.
It is hard to find some used ones in my area but I will keep my eyes open.
