well, after a few horrid weeks of getting 200 miles to a tank of premium... and having no power over 3k rpm... i bit the preverbial bullet and bought an aftermarket cat... bolted it on. And whaddyaknow? It works... power is restored... it now runs double strong... i actually gave a jetta 1.8t a run for the money... (until he stopped smoking the tires, then he handed me my ass) but it was close up till about 80k! The hollow cat was the problem... the backpressure creates a vacuum at the intake... that's the story morning glory. regardless though, thanks for all your input, but my gut was right on this one.
100 km/h is unsafe... it's fast enough
to kill you, but slow enough to make
you feel safe.
