Maniflow and RC40 systems are generally recommended as the best systems. I have an RC40 stainless system on my mpi and I am very pleased with it ( Great noise )

I have a de cat pipe for mine, I have never fitted it though Midas MK1 as reading articles on here suggested to me that the system was very efficient and made no difference removing....I may try now after your comment

Decat made mine more responsive, probably marginal in terms of power, but feels better. The cat flange connection with the backbox is pretty a poor design on the mpi in terms of sealing, just something to check when fitting.
