Cattless

I don't have emissions where I live, would cattless be any benefit, power wise?

Sure, probably a gain of a couple of horses with a complete exhaust system.

Also, side effects of horrible sound and carbon dump into the atmosphere.

Oh, who am I kidding, mine's catless as well. I plan on welding in a cat on mine though.

Catless sounds like **** and its not worth the measly little gain you'd get on a NA car. Just Get a high flow..

Not true.

Some dude on here has a nice N/A build and he used the stock LSJ injectors.
