Opinions of a JDM 4-1 header on an LS? pointless or not? I read on some other board that they said that a 4-1 setup is pointless on an ls because 4-1 actually works better on higher end rpms after 6800 or so. In that case an LS only revs up to 6800.

 

I might be wrong but I dont think a JDM 4-1 fits on an LS block.

 

i hope not otherwise i'm doing everything right now for no reason.

 

anyone? bump.

 

Yes, the header fits. It might not line up correctly on the collector side but that is an easy fix. It is true that a 4-1 is a high RPM oriented powerband...but its still a big improvement nonetheless.

 

nice sig. ok thanx.
