Defender snorkel HELP

Hi, I'm hoping I can get some advice here.

My partner has a 2014 defender 90 hard top (all the details I know) and wants a snorkel for it, safari style.......this is where I come in.....I'm hoping you can advise me on which ones are compatible or if I need more information of specs etc. Do people know where I can get one and if the defender needs permanent modification or if it can be removed at any time.

Thank you in anticipation of your help!!!!

Im not the best to ask as im not the most clued up person when it comes to this lark. But the 2014 defender is known as the puma. So a quick google of safari snorkels or ebay for a puma 90 should see you right.
