High Flow Primaries
Thought I would share this with you guys. Just swapped out my stock primaries with thunderbolt high flow 300 cell metal cats. No CEL. Car is slightly louder at startup and cruising, but definitely louder at WOT from what I can tell. My setup right now is: stock manifolds->high flow cats->no secondaries->muffler.

If you dont throw a code by changing out the primaries then no, the secondaries do not have O2 sensors before and aft. Its good to know 300 cell work with the car in stock trim, I had always wondered it they would throw a code.

In addition to the questions above, I would like to know if you're going to smog your car? It would be great to know if it passes the California smog sniffer test!

a sound clip would be nice

Would the cars ecu need to be adjusted if you swapped out all four for hi flow cats?
I have heard the labor to do this was expensive and difficult. Did they have any issues with the install of the primaries?

I used these 300 cell cats w/custom downpipes from my Turbos, relocated O2 sensors & bungs NO check Engine lights & recently passed stringent CA SMOG w/NO tricks on crapy 91 octane. They're surprisingly afforable & durable been on nearly (2) years now...

hows the sound under normal cruising? and im assuming it gets progressively louder as you hit it.
