I want to get a highflow cat and was wondering how these Random Technology cats hold up with our cars. I plan on using this on my series5 n/a but I will be going turbo in the near future. I've heard of people killing aftermarket cats within a few months and just wanted to get some feedback on this specific one.

Thanks

That is probably some of the best cats on the market, if not the best. We installed one on my buddies 330hp S4 a couple years back & have not had a problem with it.

Same here, big street port S4. That cat on the car wasn't an issue.

All the Porsche boys are retrofitting them as well.
