has any1 ever had a broken valve or somethign stuck in their cat? i blew my swap, rebuilt my other gsr and used same headers and cat.. think maybe a part of a valve went into my cat.. jw if that happened to any1 and jw what kinda noises it made.. thanks!

 

The brick in your cat can become dislodged or broken which would block flow and rattle around. Haven't really heard of valvetrain ending up there.

 

Ive seen it on S2000 and Rsx types that have came into are shop with blown motors from missing shifts

 

oh, bc a piece of my valve was missin when i took the internals outta my head.. thought maybe it went thru headers into cat.... ive heard of it happening a couple times.......... blown motors suck
