Hey guys. I just failed my emissions test a month or so ago. I've got the Hogan High Flow cat on it so that I'm sure is the culprit. I would like to add a secondary cat (generic) in there to pass the test, then remove. Does anyone see any problems in running 2 cats in line??
Also what diameter are our pipes ? I've got the Magnaflow catback on and I was guessing it was 2 1/2 inches.

I found a generic cat at part source for $80 at part source. Not sure what happened to the original cat, was a few years ago I had it taken off.

Thanks

 

I have a stock cat for sale,bolt right up $60 shipped in the good old USA

 

I think I've heard before that a tune can be made to do better in those sniffer tests, but we don't have any test here so I don't know for sure.
