invidia High Flow cats

I am currently looking at a set of Invidia HFC to go with my muffler delete, I had a few concerns

is anyone currently running Invidia HFC?
Any Cels with it?
Do I Need a tune? I only have muffler delete
power gains?

I have seen 8-12 whp gains on the dyno before from a basically stock Z before depends. Installing high flow catalytic converters is worth it you will see whp gains from it. I would install the AAM Competition high flow catalytic converters with your muffler delete over the Invidia high flow catalytic converters. The AAM Competition high flow catalytic converters I installed before had excellent fitment,were excellent quality,and lasted a long time until I sold them.

FYI you will not need a tune if you install high flow catalytic converters on your Z you will be safe. Aftermarket high flow catalytic converters are a lot less restrictive than the Genuine Nissan stock OEM catalytic converters. Also you will not get a cel if you install aftermarket high flow catalytic converters. When I installed my AAM Competition high flow catalytic converters I did not get a cel or check engine light on my Z.
