Z1 High Flow Cats Review/Complaint

Quicksilvers · 03-19-2018, 06:31 AM

You are not the first person I heard that their Z1 Motorsports high flow catalytic converters failed. I wonder what company is making their high flow catalytic converters for them now?? You should that done some more searching before you made your purchase. I would have not given Z1 Motorsports my business. If you are not going to run catless test pipes than I do know that AAM Competition and Fast Intentions have a excellent track record with the quality of their catalytic converters.

Update if anyone is considering purchasing these. Decided before tuning to see if o2 sensors needed to be replaced, and they did.

I did notice that when I was taking the sensors out, one of them lost the steel wool I used for the cheap method

The z1 gaskets are junk and leak, which I found out after installing, so after I install the fast intentions gaskets I’ll give the mounting brackets another go and update on those as well.

Since it’s warming outside now, I have been able to get more of a feel on the sound from these. I do feel like I lost power when compared to test pipes, and it doesn’t have that loud, raw sound anymore.

Your cats failed or the gaskets?

They should be under warranty, shouldn’t they?

I was considering gutting mine if that happened and using them as resonated test pipes.

Tried to browse for any warranty information on their site and couldn’t find any... still waiting for a response from them on the quality of the gaskets, but I’m assuming since I left a review of their product that was less than 5 stars I’ll get ignored by them.
