Solid fab makes better gains IIRC
Not sure if the k-tuned sits nearer the underside of car or not, someone might confirm
Pretty sure it's oval to help with clearance.
Isn't the k tuned one of the loudest systems you can get?
3 inch is droney enough, I'd stick to a 'silent' system personally. My tdi 3" quiet system is pretty loud still!
