Had my blower on less then a week. I've been getting on since I've had it but i wasn't expecting my cats to fail that fast. I have highflow ARH cats. Turned up the boost to 12lbs, made a couple pulls felt pretty good. On my way home leaving the shop, made a pull in 2nd switched to third and the car bogged, check engine light blinked a couple times and went off. Got off the next exit and drove it back to the shop. Cylinder 8 misfire code popped up on the scanner. He cleared the code, ran a couple test everything checked out fine but the car didn't have the same sound that I'm used to hearing. Took it back to shop. Took the exhaust down and noticed the driver side cats were 50% clogged. Cut the old cats out and welded some 3in stainless steel pipe in its place. Mechanic said I don't need a retune so I should be good to go. Moral of the story is get rid of your cats if you have a supercharger. I hope I didn't mess anything up
