Build up already :oops: for us guys they live in states with smog testing high flow Cat are our only option. No smog test go catless and tune out the CEL. Hopefully there's tuning ability at some point for the 24's..

I am in CA, will the high flow cat option pass smog? Is tuning required to get it to pass smog/tune required in general?

No aftermarket or performance cats/downpipes are allowed under CARB regulations. You are only able to install OEM or OEM equivalents after failure of factory components. SPD, or any authorized dealer, will not ship them to California because of this.

I have yet to have a smog station do a visual inspection, only worried about the obd smog part of it. What kind of mpg increases are you seeing with your cats? Honestly would be happier with increased mpg's over power haha
