Anyone know if there are any headers for the CTS-V LS6 that fit? I'm looking into getting a normal CTS, then having a worked over 427 LSx engine dropped in it. 514 HP and 503 lb-ft of torque never hurt anyone did it? :worship:
I just wonder whether or not there are headers that would fit this application.

I wouldn't dismiss the stock CTS-V manifolds too quickly. They are actually generously sized and not as much of a restriction as you think. They also don't have the sealing/durability problems that headers typically do. 500hp through these manifolds is possible. Look at the Lingenfelter CTS-V package. It runs 510hp and 530ft lbs through the stock manifolds and cats!
