I know you make a living doing this kind of work, so you probably know how it fits by now, judging by the pics, but I had to angle my runners when I did mine for clearance issues. They are both angled up and to the front. Just trying to free you from the problems I encountered. http://i438.photobucket.com/albums/qq103/Jocxellier/For%20sale/20120226_160014.jpg Your's look way more professional, so keep it up, you wont regret it!! Might contact you in the future for a exhaust manifold
