Why would you do headers then choke the flow with only 1 cat? I never understood the reasoning behind that.

Emissions requirements for registration and space issues under the car, especially lowered.

Mine is bolt in. I can install or remove my cat in under 10 minutes with only a 14mm deep well socket and ratchet. Looking at the 4" exhaust, but still torn on it, maybe a 3.5" will do.

This cat is rated for 600hp, so theoretically it shouldn't slow me down

Nj requires emissions, so I need a cat... I can get away with deleting air and egr as they don't pop the hood or sniff test.

Pcm4less tuned them out also so my cel is off.
