DC Sport Headers?
 

Does anyone have these installed? They look a little too good to be true, I was just wondering if anybody had these installed or had seen any dyno info on them.

Don't think anyone here has them. Someone here said that they are cheap knock-offs. The best headers for the Z is the Z1's, FI, and PPE in no order. It will take someone 1.5 hrs on the right side and 6+ hrs on the left side. Trust me. ;)

Oh im absolutely not going to install them myself, learned the hardway on my gears. But i did want to get a tune but i wanted the tune to be the last thing i do performance wise. I was thinking i would do shorty headers, the intake plenum mod (z1 or motordyne, leaning more towards motordyne) have then all installed at specialty z and let them do the tune after that.
