    Red face Protege5 Cat Replacement

    I recently (1 year ago) inherited my dad's old Mazda Protege5 and lately, the P0241 code keeps on popping up. I replaced my O2 sensors in March, my spark plugs in July, so naturally, the last issue I need to address is the cat. Anyways, I went to three places today and two of them underestimated me cause I'm only 17, and tried to convince me that I had to pay $1,445. I got a referral from one of the more honest mechanics there that pulled me to the side and the other guy is only charging $225. Whoo!

    Or you can install a new C.A.R.B. compliant pre-cat for around $250 US plus labor...

    I swapped my cat out recently for one I got off of eBay. It said 49 state compliant, but passed California smog just fine. It took me about 1 hour total to swap them in my backyard on Rhino Ramps.
