Best SB exhaust manifolds

[LS-300]

I know this has been covered but I haven't been able to find the info. What I'm interested in is the best flowing cast exhaust manifolds casting #'s. They don't have to be a set as they came off a specific year SB. If the combo look too expensive I might consider headers like the Tti's.

Two good articles to read on exhaust.

After reading this and comparing cost/benefit for a street car I went with Summit brand (flotech) headers.

Both good reads. I'm still not sure which way I'm going but headers are defiantly an option. My biggest concern with headers is ground clearance. Hit then a few times on speed bumps or anything else and the gains are gone!

Member Treblig sells some SB exhaust manifolds that are probably the best flowing for the price. Look in the mechanical parts for sale forum.
