One product must have several urls. How do that?

I use 3.0.2.0 opencart, default theme.
sample1: kts-dizel.ru
/forsunki/forsunka-33800-45700-denso-095000-5550/
/forsunki/forsunka-33800-45700-denso-095000-5550/095000-5551/
/forsunki/forsunka-33800-45700-denso-095000-5550/095000-5552/
sample2: arc.com.ua

I think there is need to change routing logic, but i don't knot how. Or write extension. And i hear there are difference in route build if using seo url.
Store will have about 1000 products. Any solutions?
Is redirect extensions like: "redirect manager", "external product links" can handle this?

I would not suggest to do this. Each product must have their own links.
