Dang, no Del Rio.

joe@vwvortex

not sure if they asked or if DelRio chose not to participate. I'm not even sure if you can buy just the manifold separately or not. Just be glad you sold your Dahlback unit :-)

I didn't sell it. Delete this whole tread QUICK!! ;-) I've always intended to but haven't gotten around to it. Oh well, live and learn. And there will still be someone who will want it for the looks and still obvious performance increase. :-)
