Cutouts are the way to go.

If I did it over again, that's what I would run, so I could run normal sleeper mode then when needed press a button and let the big dog breathe!

Cutting the 3rd cat, resonator, and mufflers off and straight piping a 3.5 EB will probably be the worst modificaiton you will do to your SHO. The drone will be unbearable inside the cabin. Also the 3.5 EB is probably one of the most terrible sounding engines on the planet.

There aren't many cat back exhaust systems for our cars because they aren't in high demand. Off the top of my head Magnaflow makes one.

Nobody wants to mess with catless anymore. It’s not worth the fines and BS from the EPA which is working hard to **** our industry. People don’t realize that the EPA like the IRS is one those really powerful three letter agencies. With all that said, just get catted because they work just as good.

I took my exhaust off and it’s the first time I like the sound of the car and the turbos sound great! People finally stopped thinking I’m a cop too which is another huge added bonus. I need to need to figure out some side pipes!

In July the supreme court took away the rights that EPA had for the past few years. They can longer give fines or fight against anything about motor vehicles. New or tuned. They can still do what they do but not against cars, parts or altering software.
