What is the difference between these manifolds?
I am re-doing an STS rear mount turbo build and am going to put some manifolds back on versus the ol long tube headers.
What if anything are the differences between exhaust manifolds from our 1998-2002 LS1's and the exhaust manifolds from a 6.0L truck based engine?
I've heard for some reason the 2000 and up exhaust manifolds on the fbody cars flow better than the 1998-1999's for some reason.
Any help would be great.
