Default How quick with stock exhaust manifolds?

How quick have some of you gone with stock LS1 exhaust manifolds on an F-body? At what point are headers actually showing an improvement worth the time and money?

The fastest Ive seen a stock ls1 f-body go was a 12.99. It was an 02 SS with a M6 and the guy could drive good.

Time and money?

Headers are cheap and maximize gains elsewhere.......ie cam, nitrous, etc etc.

And easy. Not too many other mods that are easier IMO

Only people that keep manifolds are those that are limited in class, being sneaky, or turbo'd.


It's worth it if you are going n/a for sure.

I went 7.56 in the 1/8th with stock manifolds, hoping to go 7.2x 1/8th 11.5x 1/4 this year with them though.


This was N/A, you know, nitrous assisted

12.42, @ 113 w/ 1.89 60'. Next mod is 4.10 gears. Hoping for some low 12's, before cam and headers.
