No they did not. The pieces that made it into that section were really small. The factory cats almost turn to sand when they break but the aftermarket may be different. I havent heard of anyone hurting their mufflers however. If you dont need the cats I would ditch them

I gutted them, changed my BOV, and updated tune. Went from previous 570 at 6-7 psi to 606 at 8-10psi no other changes really...
Could have been leaking boost or could have been really clogged cats or a combo of them both
Needles to say I was happy with the new numbers

I replaced my high flow cats with straight pipes because I felt like it, and I had a sneaking suspicion they were on their way out due to some small clues. I'm glad I did, because they're basically maracas now. The catalyst just melted and bunched up on itself, but didn't break apart. They were fine when I put the blower on a few thousand miles ago.
