    Default 355 Cat Problem

    My right cat ceramic core has come lose. Found a replacement on ebay, in transit from CA. This will be the 3rd cat installed! 355 cat failures are very common!
    Considering having my old cats re-cored. Any of you know of a reputable company that offers this service. Fabspeed does but, from my understanding, very expensive.

    Hey Frenchman, are there aftermarket ones that are better?
    Birdman308 for parts and tutorials!

    Birdman, had Hyperflows, great product but too loud at idle and cruise. Stock cats are quieter. Car howls when the bypass valve opens. Best of both worlds!
