Catco H Pipe es no bueno
 

I've had it since October and the Cat on the driver side already fell apart. Sounds like a cowbell ringing in there. I thought it was the tranny, but when we dropped the exhaust we could see the honey comb inside spinning around "clanking". The hangars didn't fit worth a darn either. I had to reweld the hangars to get it to align up with the header flanges. My engine's running great too, so I know a rich condition didn't cause it. Just letting you guys know in case you're thinking of buying one. It is the cheapest high flow H-pipe with converters in the Summitt catalog. I guess I know why.
