Where to get atalla exhausts in UK ? Replacing Stock xj6 exh

[ko5i]

Hi im interested in Atalla 4x1 exhaust for xj6
https://atallaescapes.com.br/index.php?route=product/product&product_id=340
But they dont send it outside of brazil, and i cant find it anywhere else.
Anyone know where or how can i get this exhaust to UK it costs 1000 brazilian real so in pounds its about 200£.
Or where can i get some louder exhaust than stock one cheapest way.
i was thinking of buying yamaha r6 headers 5sl 2003-2005 and heating it up and bending a bit so it won't touch the oil pan and then getting some ''slip on'' and drilling a hole for lambda sensor. It would be a bit of work i calculated would spend about 80£ for headers gaskets a screw for lambda sensor all together would be about 150£ and then i would have to get some slip which may cost about [depending on what slip] 30-200£. Or just getting leo vince sbk exhaust where i have 2 db killers and can adjust sound however i like but its kind of expensive 600£ for exhaust thats like 2/5 price of the bike.
Any idea guys about these atalla exhaust in uk

Thanks for help !

Year is 2013 xj6 N
I decided to go with the R6 headers for 70£ in pretty good condition i will try to heat it a bit and bend it as people said on other forums. Then i will fit in the screw/bolt for o2 sensor and get some exhaust can

R6 headers.

Are you a fish?

I was going to suggest R6 headers, they only need a bit of abuse to fit and they open up loads of can options.
