I've been talking to Kooks about a set of conversion headers. As you know, the exhaust ports on the LS7 are different from the standard LS port and I'd like a bigger primary. Although I wouldn't be scared to run the Art Morrison headers I have now.  |
we are using the Dart heads on this car and I would like the bigger primary also . Let me know how you make out with Kooks. I have a few things working also , I will let you know how I make out also . Thanks
