Better mileage without cat?
Since I decatted my car I noticed a better mileage per fuel tank, can the decat be the reason? Or did I become a ***** driver since the cat is gone 
? It goes a hell of a lot better then with the cat...

good question, I've just had a sport cat fitted (sound clip to follow) and will run a mileage test this week to see if it makes any difference. Not sure how it would but you never know.

Well the cat is very restrictive and it is possible you need to press on the gas less in order for the turbo to spool up faster and therefore indirectly achieving better gas mileage. Although I doubt it. I am having the 100cell sport cat installed this week. Who knows i will see if I see any difference also.
