Hey Z1. ETA on those headers?

Joepro

All I can tell you all is after I put the headers on there was a significant change in how the car ran on the top end, I said this before, we are way to wrapped up in numbers, I might pull mine out in February and go dyno when it is 20 degrees outside and Ill probably hit close to 340 if I suck in in that cold air on the dyno...Here is my final verdict, IF you can do the install yourself they are worth it, if not, forget it, save the money for something else.
