It is still unkown exactly will be done with the tests.
Good point... Texas is now using California as arole model for future emissions testing....:banghead: I have been thinking(wanting) to keep the stock downpipe until that time..

I dont think it robs that much power vs a high flow cat.. Maybe I'm wrong..:confused013:

Anybody got a dyno graph showing stock exhaust vs. free flow straight?
