Any exhaust modification behind the cats is legal, Removing the cats is illegal, Getting high flo cats is legal.
You can remove the resonators and mufflers and still be legal.
If you have the PE, a muffler delete will throw codes and send the car into semi limp mode.
Just FYI for anyone who wants to do it.

Does removing the resonator increase horsepower?
The resonator delete can sometimes improve your overall horsepower rating if there is heavy buildup within your vehicle’s exhaust system. Your goal is to create a little back pressure on the engine to create better efficiencies, but not create something that is close to a blockage.
What is a resonator delete?
Corsa’s Resonator Delete Pipes install quickly and neatly in-line with your vehicle’s cat-back exhaust. These pipes allow you to remove the factory resonator from the exhaust system to create exceptional flow and sound. Like most Corsa products, direct-fit delete pipes mount without modification or welding.
What is the difference between a resonator and a muffler?
The #1 Difference Between Mufflers and Resonators
The main distinction is that a muffler is designed to muffle the overall volume across all RPMs, whereas a resonator is designed to eliminate unwanted resonance or noise at a particular RPM, also known as exhaust drone.
What happens if I remove my resonator?
A resonator makes your overall exhaust note louder and more aggressive. It’s not quite a straight-pipe, but it isn’t too far off. Resonators also have less baffling and don’t reroute exhaust gases as much as a muffler. This reduces back pressure, potentially freeing up a few horsepower.
What is the purpose of a resonator delete?
Function of a Resonator
A resonator installed as part of your car or truck’s exhaust system serves one main purpose — to resonate. It’s sort of an echo chamber for your car’s exhaust, preparing all of the loud noise coming from your engine for the muffler to silence it. But there is far more science to it than that.
Does cat delete increase HP?
Cars that have their catalytic converters removed experience an increase in engine horsepower. Removal of catalytic converters from cars allows exhaust gases to exit their engines much faster and at higher levels.
Does straight pipe reduce power?
You want an exhaust system that facilitates scavenging when the engine is going as fast as it can. A straight pipe, for example, can cause exhaust gas velocity to increase. This will likely reduce engine performance below 2,000 or 2,500 RPM, making your vehicle a little slower to launch from a stoplight.
Does removing mufflers increase horsepower?
Removing the muffler will significantly increase the exhaust flow while reducing harmful engine back-pressure. In most cases, a muffler delete system or a set of aftermarket mufflers (or axle-back mufflers) may do more harm than good and result in less horsepower.
