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?

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. Period.

Oh?  I just looked.  My oem muffler is not straight through.  It is loaded
with baffles and "U" turns.

So you're saying that any spark will do, voltage ** Plug Gap** and duration
have no effect.  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.
