best turbo cat

[charofire]

What brand of aftermarket cat holds up the longest in a turbo application? Assuming the tune is proper...

[Kyle in NO]

I'd go for the Random Technologies metallic substrate catalyst.

A gutted cat. Interpret that as you will.

Whatever one TCD uses on his turbo exhausts was excellent for me. Held up to abuse and passed CT emissions easily. Magnaflow 3" center-center. Probably the 93509 unit, but I don't know for sure.

I smoked a Magnaflow sometime during my street/dyno tuning process . My recommendation would be to get the tune as close to correct before installing it then once installed, you can dial in for emissions if required.
