[s-cars] bad cats

[Bill Clancy]

FWIW  -- I am very disappointed with the Stebro exhaust.   It's loud at
idle, and has an annoyingly loud resonance between 2600-3000 RPM.   I played
phone tag with them for a while -- attempting to get them to offer a
solution (such as a different muffler) but I could never get a live person
on the phone.

For Cats, my old ones were rebuilt at a cost of $600 each.    There is a
place in CA called catalyticconverter.com.   They sent me two Cats for $275
each, but they didn't line up right.
If I were to do it all over again, I'd take it to a custom exhaust shop and
let them deal with it all.
