An this is on hold for now, other thing I is a serious family issue( mom). So my thoughts and efforts are elsewhere for now. I'll update this when it happens,

And I do plan on getting dyno runs done before and after my retune.

Thank you

Mike are you going to have these installed before the snow hits or wait until the spring? I'm super interested in headers and I'm curious how these fit for you and what the gains are. PS I hope your mom is feeling better and I wish you and your family a very Merry Christmas!!

I just ordered Stillen headers ceramic coated. I want to keep my FI RHFC's so went that route. Z1's may be a hair better, but maybe not.

Update. Mine are going in on Wednesday and going to try to get to the dyno on the 19th

You could have just bought the DE flanges and had the FI cat flange changed. I'm keeping my Z1 HFC's just changing the flange

Bad news., I'l lbe selling these. They don't fit. The drivers side wont clear the motor mount! Passenger side was fine

I'll have pics up tonight on the FS forum. $750 Shipped with all the hardware and flanges so you don't have to change you cats.

Huh I guess these aren't the same as Z1 headers then. Chuckie got his on from Z1. Unless the motor mount on the AWD is in a different spot than on the RWD models. How far off was it? Was it close or not at all?

I just called Stillen to verify and spoke to Ivan there. He said they will fit the AWD models. Told him I have a 2011 AWD sedan and he says they show their headers fit RWD and AWD. So I'm going to give these a chance. I will let you know if they fit and then after you sell those one you could use that money to get Stillen 304 SS and still have $100.00 left over. The battle is not over yet.

Yea I'm watching you with lots if interest especially if they fit. The mount has to be different, AWD has a little more weight upfront and I look at chuckie's pics and his looks exactly like the set I have.

Really tuff part is I just spent $600 to remove the stock headers look at them and put then back :/
