What Brand Of Cat Would Be The Best? Davico, Eastern, Or Walker?

[J Random User]

1996 ES300 with the wasted-spark 1MZ-FE, where the whole cat needs to be replaced and you can't just replace the front pipe like the 94's

They're all about the same price about $220 give or take.

PLEASE don't say Bosal or Magnaflow, as they are NOT direct fit!! (I read about that on Amazon product reviews about them and also other Toyota-related sites)

Also, what about new bolts? What size are they so that I can get new ones? (usually recommended since they rust really bad) What to ask for at the hardware store? Or are they usually included with a cat?

And what's the difference between standard load and premium or ultra load?

Is M10-1.25x 40 the correct bolt size?
