Best/Light Exhaust for Rally/Racing?

[Brushwood69]

Hi, Have a smashed up 182 scorpion exhaust following my recent rally adventure so looking for the best replacement so looking for suggestions. Can I run a single exit 172? Are the mountings the same or different because of the wheel well? I want a light weight, small as possible rugged unit so open to suggestions. Thanks
