Whew, I wish I was as sure of anything as you are about this. So Walker, Borla, Edelbrock, Schnitzer, Ansa, Supersprint, Techtonics etc. etc. are all selling snake oil right? If a plugged cat reduces power, why won't a better flowing cat increase power? > >As long as the small diameter exhaust maniflods with their large bends and >unequal length come off the heads, adding a larger diameter muffler and cat >will not improve performance.\ Small diameter primaries are what maintains torque. You want tight bends? In addition to our Vanagon I have also placed a 2.25" stainless **cat back**exhaust on my 2.0 liter 16V Jetta. As a result it is a rocket!! Techtonics has the dyno sheets to prove that this exhaust does increase power. The auto aftermarket is full of BS and false claims. But... free flow exhausts even without a 32" primary, equal length, rotational collector header, can work.

It is loaded with baffles and "U" turns. > >As for the Jacobs ignition system, this won't add HP either.

Say what??? With the variables that we all see from our digifant FI, which is often providing a marginal mixture, you think that a bigger, hotter spark wouldn't fire some of those marginal charges that might otherwise misfire? Think about it. Our Vanagon is quicker. My butt does not lie. Gary |
