my 348 was sold in italy, shipped to Japan and found its way to the states. my question is about the cats, my car doesnt have thermocouplers that i can find. the cats look alot like the pre mufflers #44 on the diagram attached. WHAT DOES "VALID FOR SA" MEAN? anyone else have this setup? I'm gonna get test pipes via gothspeed but wanna make sure everything will go smoothly. http://www.ricambiamerica.com/parts_catalogs.php?M=FE&P=&V=diag&I=3073 thanks for looking.

Just a wild guess but perhaps SA=Southeast Asia. I'm sure Daniel @ Ricambi will set us straight sooner or later.
Saudia Arabia (check your air filter for sand! Since it's a pre-muffler and not a cat. it does not need a thermocouple. Cats. get hotter than the actual exhaust gas entering them (I believe) through a chemical reaction which ends up reducing emissions. Your pre-muffler is not going to get super hot like that so no need for a warning via a thermocouple.
word up, my next question is it worth it to replace pre-mufflers with test pipes? are the pre-mufflers restrictive at all?
By definition (muffler or pre-muffler) it's reducing sound somewhat so the choice is yours. I know I would replace them. Might even get a tiny hp gain, although it wouldn't be noticeable. Perhaps the market for your car didn't require emissions reduction then but maybe had noise restrictions??
