Sorry it took some time to send this back but thank you.

 

What approach would you recommend in lieu of gutting the cats? A number of states have annual emissions tests that would preclude this as an option. CA in particular, is real strict on modifying emissions equipment. You might wind up getting your car impounded until you get it back into compliance.

 

If your state is strict about emissions components I probably wouldn't recommend this.

Although you would never be able to tell anything was modified by looks alone. As you still use the stock downpipes. The cats are just hallowed out.

Only way you would be able to tell is if the check engine light was left on or they do a snuff test with the exhaust. Visually it looks the same as stock.

I live in md they just plug my car up and start it up and thats it.

 

Jason, VA and CA are both pretty strict on emissions. They both do the sniff test. This may impact MD cars as well if you plan on selling it to someone in VA.

 

In those states I probably wouldn't recommend this mod or running any sort of cat delete pipes.

I know in OH you can register your vehicle as a "collector" car and it a lot of times gives you a hall pass for emissions testing. Obviously there's probably more requirements to attain these plates but it might be something to look into if you have an extensively modded car and want to drive it on the street.
