Worth the higher price tag...
The previous owner of my truck had installed a Flowmaster exhaust system. It sounded decent on the outside, but it was loud in the cab. The Corsa system blows the Flowmaster out of the water. It still sounds healthy outside the cab, but inside is whisper quiet. The Corsa system is also much better at letting the truck breathe when the cylinder management system kicks in (ECO mode). I'm driving an entirely different truck - more power, smoother acceleration, and better fuel economy.

Start to finish install in under an hour with 15mm and 13mm deep socket and 13mm open end. Driver side lined up perfect, passenger side back hanger could be a little shorter. Took some time to get it "almost perfect". Sounds good on throttle could be louder at idle. This is not a daily driver so I could tolerate a loud idle.
