Based on my experience in the past with MHD (which was awesome), I didn't switch the sparkplugs, as at that time for the n55 engine, you didn't really NEED to do that unless you were upgrading the turbo. That car ran perfect without upgraded sparkplugs. MHD's numbers are somewhat accurate but there's a variation given different quality of gas used etc. No, removing the particulate filter will not be essentially straight piping it as you will still have the muffler (and possibly still the resonator - but you can confirm about that).

PS. Where are you located in Canada?
I got a 40i too! I would have rather had the actually gas version rather than they mild hybrid.
Interesting, for the downpipe what are you going with?
I have to replace the spark plugs regardless but gapping them was an interesting suggestion.. regardless more than likely I’ll have it on and ready to go within a month or so. I’ll post back. I’m in Winnipeg.
