Default Catalytic Converters

I'm looking into purchasing 3" High Flow Catalytic Converters to be welded into my TSP True duals...
Does it really matter which brand i get at all?
I was looking at these, anyone ever used them?

They will work fine right?

Anyone have any input? Does it really matter what catalytic converters i get or are SLP high flow cats overpriced for a reason?

anything will work as long as it clears. and for what it's worth a couple of my friends that work at exhaust shops said the high flow ones are not any better than regular aftermarket ones but the price on those ones is good so I wouldnt worry about it

I don't think they're legit. Try contacting them and see if you can reach them. I couldn't despite several attempts.

They'll fit but I've never heard of that brand before so I don't know how they flow.

installuniversity.com has a tech article showing the flows of various cats compared to stock. I think SLP and the magnaflows did much better than stock and a couple of other companies (I can't remember which) did the same or worse.

The metallic core magnaflows flow really well at over 600cfm IIRC and I have seen them for about $120 ea. When i was searching cats I thought they were the best bang for the buck.

I just bought 2 3'' Carsound Magnaflow cats for my TD setup... I had 1 on my 94 formula and noticed a hell of a gain over my stocker. The sound was better too.

I've got the same setup as you (TSP Duals) and when I took it in to have cats welded up they used the previously mentioned Magnaflow ones.

I only put them on for inspection but I can tell you that they pass Cali smog no problem so long as someone will overlook other things......
