Hey Mike,
You were asking about Greg's inconel manifolds. So here's the latest news;
The manifolds are finalized and being tested on Seb's car right now. Without changing anything on the car they produced +30rwhp and +50lbs rwtq. The EGTs are lower. And boost is solid all the way to redline.
So you can call Greg now and get all the details you want. I hope you get them soon your car will be a low end monster with those things.
