New cats

Recommended Posts

Buying one through the exhaust shop that will weld it in for you may be cheaper than buying it yourself and having it installed. If you live in California or New York the replacement will need a CARB number or else you will fail visual smog inspections.

Why does it need new catalytic converters? If they're fouled, you have something else going on to make them go bad. If all is right with the engine health, they are designed to basically last forever, so I would be looking at other reasons as to why they are bad.

Lots of us take off the OEM down pipe which has cats and replace it with a 3" catted DP and a Cobb AP. The cars runs better and still passes emissions test. Gets better MPG too.

305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).  CHECK your oil, these cars use it.
