Did a search, with nothing specific coming up.

...what's the latest and greatest in the world of hi-flow cats? I had to remove my old magnaflow to get the SFC's on, and I'm currently cat-less. Figure might as well put a NEW one on and ditch the old one.

3" in / 3" out

 

the "spun metal" cats are the highest flowing ones ive heard of, i think magnaflow makes them

 

Random Technology?

 

OK, found on another board where the "metal" (spun metal?) subrates are better than the ceramic substrates. Not sure about magnaflows replacement cats, but their off road cats ARE metal, not ceramic. ...which is what I'd use.

Seems to be about $180 just about everywhere I can find. Part number for the 3 in 3 out is 14109, in case anyone is interested in doing some reading.

 

mag 36019 cat is 3 in 3 out and carb approved.

 

the highest flowing cat is the random tech cats. but they come with a price.

 

...lucky for me I'm not in California! ...plus, that cat has an air tube which I don't need. Thanks though.

...I think that actually I'm gonna fly catless for a little while while I re-think my exhaust plans. I've contemplated longtubes in the past, and "might" look at the idea again. Please no tree hugging commentary as the potential fine alone is reason enough to put a cat back on at some point. Just no point paying for the labor now if I'm only gonna change it in the near future.
