Exhaust Question for TJKJ

[ptsb5a]

OE cats are about the highest flowing cats on the market('03+ cats) and hence the very high cost.

I'm glad you're on this forum. Learning lots every time I read one of your posts. I had no idea that the factory cats would be considered high flow. They're probably built by the lowest bidder.

REALLY? (dropmouth) WOW! I seriously would have never expected that! and I'm not being sarcastic! I would've thought quite the opposite! Man that blows my mind, I figured Magnaflow High Flow cats would be less restrictive...well that right there alone would save me a bunch of money if I decided to do an exhaust...

Is that in all make and models or just the Liberty's?

All makes and models,more so for '03+ vehicles due to the elimination of 2 different emissions(Cali and federal).Most OE cats are actually made by either Dynomax or Magnaflow.

Not when they have to foot the bill with a federal 8 year/80,000mile federal warranty that is mandated for the US for cats(also the PCM for california only).

Still, I do appreciate every little nugget that you let fall onto this forum.

We have similar legislation in Canada. The vehicle manufacturer is responsible for all emissions control devices for 7yrs or 115,000 kms. Including the PCM. So things like O2 sensors, and cats are warrantied for a bloody long time. Too bad I used up the mileage before the time expired. I've had my KJ for four and a half years and I'm already well past the 115,000 km mark.
