Headers or OEM manifold which one ????

[opfor2]

Yesterday while I was pulling my AC evaporator coil out of my 90 K-5 I noticed that my left passenger OEM exhaust manifold was cracked. What should I do? Should I just get an OEM replacement of should I get a set of shorty headers? I already have a hi-flow cat and a Flowmaster cat back exhaust installed. All suggestions will be helpful.

If going with headers, go long tube or go manifold.

My opinion anyway. If you are going to be dealing with the potential hassles of headers (buy ones that people have experience with here) you might as well be getting as much out of them as you can, and for most of us, the low end efficiency of the long tubes is where it's at.

This issue has been hashed out a lot of times on this web site .

My cousin cracked a manifold on his early 90's Chevy Z71. I think it was a 91. Anyway for cheaper than replacing the manifolds he got some shorty headers out of summit that were smog legal and connected right to his stock exhaust. Search "Summit Truck Headers" His have lasted 2 years so far with no problems.
