Anything with cats will allow you to pass emissions. Just don't go off-road and you'll be fine.

You asked what midpipe, I said stock. As in stock H pipe with factory cats. High flow cats might pass, depends on how strict they are.

What kind of emissions testing is done there? They do the OBDII scan where I live for emssions testing. I've passed with 2 cars that had no cats on them. Just needed an O2 sensor spacer.

Just get a catted pipe if you're worried about it, though you COULD have trouble, like some said, even with hi-flow cats if there's a strict sniffer test. If you just need OBD and visual hi-flows should be fine. If you just have OBD, you can try to trick it and get away with no cats.

Going to get the MRT stainless mid pipe from brenspeed. That should take care of the emissions code i keep getting...now need to decide if i want to swap out my axle back Bassani big mouth with frpp bullitt style or keep it. Bassanis have the dreaded drone at highway speed.
