Catback

A catback exhaust is an exhaust system which has catalytic converters still in place. It refers to the components that run from the rear outlet of the catalytic converter all the way back to the exhaust tip.

I prefer a catback exhaust over open headers, which are too noisy.

Round Body 

The term 'Round Body' colloquially refers to the 1999-2002 Chevrolet and GMC pickup trucks/SUVs, which are part of the GMT800 platform. This designation distinguishes them by their smoother, more aerodynamic, and visibly rounded exterior contours compared to previous generations of GM trucks.

Just picked up a round body chevy, not a fan of the cateye look.
