I hadn't heard of the 625s sean - I'll have to take a look at them. Why not BC I beams? I know you said that you weren't a fan of them before, but I looked and didn't see anyone with issues either. If there is a reason anyone knows why I shouldn't - let me know.
If I can keep the MAF - I haven't seen many
people over 500 WHP with it - and I'm having trouble finding a good sized intake. Initially I was going to go with a KStech and scale the MAF. Then just get a coupler to go to inlet, then tune, but I don't know how well that would work.
As for Fobia - The guy doing the exhaust work will be able to do just as good of work as fobia, plus he's local, and hes been wanting to get into the subaru market. He offers a lifetime guarantee against cracking.
I think he'll be able to handle my car.
Didn't know about any snapping cosworth stuff. Compared to other companies volumes, there sure is a lot of negative feedback about the Cosworth stuff.
