High Flow Cat replacement?

My high flow cats that came with the ARH longtubes are deteriorating. I've noticed that the exhaust note has become increasingly louder and I'm getting O2 senor check engine codes.

I've looked around and am not sure what to replace them with. Any suggestions?

Thanks.

I see that the SOLO converters are for OEM replacement. I'm looking for cats to replace the ARH aftermarket, universal style ones.

Sorry to hear your having trouble with your Cats! How old are they and how many miles?
Maybe a forum sponsor will chime in for some replacements!

Had them since 2010 with very low miles as my car is just a weekend, summer warrior.

By any chance have you gone forced induction or a cam setup? I see you have a lot of driving/suspension upgrades. Do you go to the track at all? Just wondering if maybe you burned out your cats.

There is a guy in the classifieds that has brand new SOLO HFCs for sale.

You need to talk to ARH about this though.
Low miles and no FI shouldn't have wasted a set of cats unless the tune was horrible. But if you were tuned those codes should have been turned off anyway.

No F/I, but I do track the car. I'm thinking that I burned out the cats too so not a big deal to replace, just want to know which replacement ones to get.
