Catalytic converter - Cal compliant

[88olds32]

It's a toss up between Walker (pn# 80822) or Magnaflow (pn# 332015). The Walker is about $70 less, but the Magnaflow appears to have more internal size. Both are universal fit. It will be installed into an all stock Olds with a V8 307. Anyone prefer one brand over the other? Or, is there a better manufacturer out there?

For CA you will need a direct fit and it must be a CA compliant model. Some manufacturers sell a 49 state converter and a CA legal model.
