Guest vas930 Posted 29August, 2012 Report Share Posted 29August, 2012 Hi, Wet. I see you have asked this question on pelican. If you use the search on that forum you will find all you need on the subject. Check the racing forum and do the same. The main question is heat or no heat. After that the answer is clear. Here is a start http://forums.pelicanparts.com/porsche-911-technical-forum/692154-billy-boat-headers-muffler-anyone-before-after-comparison.html If you post the question on the Racing section you will find the best for power, without heat.
