Whats a good X-Pipe to match with Akra slip on exhaust

I've recently purchased an Akra slip-on and looking to combine with cat/catless X-pipes. Considering Mastermind, Gintani naming few. The Akra version are hard to find, pricy etc and I am trying to manage a budget.



Appreciate thoughts on x-pipes and on sound, performance, etc.



Cheers guys
