Backpressure to damage car?

[ianstaley]

Just a thought here, now I don't pretend to know about back pressure or Californian smog rules, but just a bit of logical thinking here, if a Lambo can have multiple turbs or a Ferrari same sort of set up then what should be the problem of getting a better flowing cat? You can't have been the first to ask this,so I would assume that a better flowing cat must be out there, just gota find it.

Yes, i tried looking for that...
there was some new emission law that came out in 2008? i believe that made it almost completely illegal to get a hi-flow exhaust system.
The link provided above has this disclaimer "Note that aftermarket catalytic converters are not legal for use in California on OBD2 vehicles (some 1994 and 1995 and all 1996 and later vehicles)."

boooo... i also tried magna flow... and when i looked for california legal hi-flow cats, they listed "replacement" parts... -_-

but yes, after receiving the answer above, i went looking for one.

meh. will probably need to look harder. that would probably be a "Phase II" of the project if i decide to replace them though.
according to the gov website... only CARB approved hi-flow cat systems are legal.
that usually means $$$. we'll see i guess. :|

Me I am lucky over here in the UK, as mine is a 87.5 MK3 (one of the first) I don't need a cat they were only made compulsory after 95.
