Let's sum this up politely: why not just keep your head down for the next 24 months? A little self-restraint might be therapeutic ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |

If you want answers regardless of consequences, so be it.
You have to look at overall flow - air in and exhaust out - and what/where the most significant restriction is.
On my XSR the major restriction was a slightly convoluted snorkel intake. Dropping the cat downpipe for a straight-thru' improved the flow a little bit and so without further modification the bike was running a tad lean. You could probably get by leaving it at that but hardly ideal. In the end I modded the airbox as well and then sent the ECU away for a retune.
I would suggest thinking about the overall system on your Z900. If other owners are always talking up airbox mods hand in hand with exhaust mods then you're probably in a similar situation as MT-07/XSR/Tenere owners and I'd definitely recommend a retune.
Either way I'd recommend taking the time to fit any system yourself, get to learn a bit more about the bike. Also useful if you need to put the original system back in a hurry, ask me how I know After that, riding out with a cat delete you'll want to assess if the bike's running lean, things like pops and bangs on decel would be a dead giveaway. "Whoa! Bike sounds cool, man!" yeah, but it's not doing the engine any good.
tl;dr factor in a retune, assess, put the original system back if you have to. ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |

Removing restrictions = more flow = more lean without a remap.
Quantifying how much each individual component affects the overall system? You can only go by experience and forum hearsay. You can be certain the original system from the manufacturer balances noise, performance and emissions well enough for the engine to last the warranty period
To echo MarJay: you may be disappointed with the results. My first attempt with the XSR left me with a two wheeled hammer drill Quite a lot of experimentation went into balancing tone and loudness. I now have quite a selection of Chinese knock-off end cans in my shed ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |
