Having already got a Ninja BB on my 04.... is there any point in me dumping the centre silencer section for a straight through pipe? (or some sort of resonated section)

I know the noise would probably increase, but by a lot?

I had a Prodrive BB + de-cat centre on my MY99, which was not loud against other similar setups.

I would think it is worth doing it. doesn't prodrive also change that section as part of the ppp package?

Not if you want your warranty intact! Dealers are unlikely to tolerate anymore than the backbox being changed I'm afriad.

If that's not an issue..

I'm told the down pipe is where the more signifcant gains are to be had, so if you're after power, more turbo nose and a slightly earlier spool up, then that's what you might want to consider chatting with a specialist about. Do chat to someone more knowledgable than me though!

Any views on the difference between the standard MY04 box compared to the Ninja? I have one on the way for delivery tomorrow.

I think it's a good BB. It's not HKS, Blitz or H&S standard, but it does have huge VFM.

It's well made, fits fine (maybe hangs a little too low), sounds superb and gives the car much more character. The exhaust note is probably not as deep as some other BB's out there, but deep enough.

I can't comment on performance gains (as I'm not that bothered about what it does for the engine) but it's sooooo much better in looks than the standard BB.

Just make sure you keep yours clean and shiny.... you just can't have a shiny enough pipe in my book
