RP Remarkable Power, RK7543 Exhaust Flex Pipe 2.25" x 12" Heavy Duty Stainless Steel 16"OL

I presume the 2.25 inlet dia in the product discription refers to the inside diameter of the end of the pipe. What is the outside dia of the pipe end?

What is the real inside diameter id, and od outter diameter. what gauge steel? is it full stainless steel tip to tip or just flex section?

I need a flex pipe with 2" inner diameter inlet/outlet. Is 2.25" the inner or outer diameter of the inlet/outlet of this product?

Will this work on a vw beetle
