Here is the part #THY-372Y-C I've been looking at. It's a tri-Y header with ceramic coating. Any thoughts on this. Says it's a idle to 4500 rpm range, do they have a longpipe version of these for mid to high rpm? Anybody running this header, if so how's the performance? By the way this will be on a 70 C-10 350 with manual trans.
