Most have zero issues with the CEL coming on with high flows. I am using the Kinetix and love them.

I've yet to see a set of proper high flows cause a CEL

Crawfords are nice; we use and recommend the Ultimate Racing ones on our own cars, also a top quality unit

Yes its possible.

Photos of high-flow catelitic converters and critiques are posted throughout this forum. Search is a great tool.

There is a difference in restricting exhaust gasses yes.

GolfinZ,

How was the reflash and tune from UpRev? How was their knowledge and attitude towards you? I will be heading up that way soon myself but your the first one I've seen that has used their product. Thanks!!

The only way u can get a CEL from high flow cats is if u have a crack. Otherwise no CEL.
