Decisions... Decisions....

I'm having a hard time deciding which way to go.

To be perfectly honest, there really isn't any activity in the X5/6 section of this forum and hardly any reviews being posted on what's out there for these cars. I've heard about many new products available for our cars, but the reviews are nowhere to be found.

I remember the early 335i days on E90post... There were at least 5-10 reviews per week for all the new products for the N54.

When I do decide on a tune, I will add DP's at the same time as it appears this will yield the biggest gains on an otherwise stock car. Obviously the Akrapovic and Supersprint are the highest quality and best known, but what's the consensus on the AR's or Ultimate Racing?? What is the quality like and any installation issues? I've read that the newer M's have a slip-on attachment in place of the bolted flange found on older M's. Is that true? If so, do any companies have DP's available with the newer attachment?

Thanks.
