Well, it’s the Log VS Equal Length Tubular manifold argument. My manifold is obviously better, being equal length, and tubular. I had a manifold like this one for about 6 -7 months and only had one crack, and that was do to the bracket on the manifold breaking off, and a broken motor mount making the manifold move while still bolted to the down pipe. The bends/welds all held up under the heat. I love this manifold; it spools up the turbo even faster then the previous one. Full-Race did a Dyno between a equal length manifold, and a log style, and believe it or not gained 68 WHP “FR Equal Length vs. Log manifold chassis dynamometer testing. Equal length=68whp gain!” http://wakesports.com/full-race/index.php?s=30105a334f0e3e8ed57644a3c06b8b65&showtopic=249 Seems hard to believe, but the manifold does make a difference in power. Now, im not saying my manifold vs. the Hahn would yield 68 WHP gain, or anything close to it, but it is definitely superior, and does yield more power. --------------------------------------- "Oh yea, well...My manifold does cool twisty things" www.EnhancedMotorSports.com
