Need to add features on my shopify store — 2

I neeed you add some features to my shopify store.

1) The main feature is the search functionality required. Ref site: https://valvetronic.com/
2) Product page: need varients to display like this: https://valvetronic.com/products/bmw-e9x-m3-valved-exhaust
The product page then needs to allow for the customer to choose certain options for their make and model and add items to cart.

If the customer chooses a catback they *must* select an exhaust tip style. If they choose only downpipes, they will not be prompted for tips as that is only apart of the catback packages.
example: https://valvetronic.com/products/lamborghini-huracan-valved-exhaust

Please write ‘Devs’ in the proposal so I know that you have read the requirements. Look forward to hear from you.
