Im in the market for either a ecu or a full system exhaust. Im not really sure which direction to go though. Right now i have a 2017 RMZ250, that im really loving, im just looking for a little more pep from the engine. i have gone to a slightly bigger rear sprocket (51T) and im still wanting it to have a little more from the mod to the top end. Ive looked into getting a GET power ecu with the GP1 switch and ive also looked into a number of full system exhaust from yoshi, rocket, bill pipes and Dr.D. I was curious how much a difference the ECU made with a stock pipe or if a full system will liven up bike enough. Thanks for the help!

In my opinion, riding an overly-modded bike is buttlickin retarded. There is always room for improvement on a stock bike, there are plenty of people out there who could perform on a stock bike (I've seen plenty make the night show), I believe modifications like ECUs aren't meant for 99% of the riders out there. It's like supercharging a Geo Metro to get to school faster. I've met plenty of kids that needed 0 of the mods they put in, actually more than the people who actually need them. Not saying that simple engine components and such are irrelevant, but it's not worth it for so many people out there. There's a fine line somewhere between waste of money and necessary.
Like I said, potential. I personally believe performance deltas on crafted engineering creates a risk of altering reliability. Suzuki designed their engine to a certain standard. A standard that tells you to replace your piston and rings at 40 or however many hours, and such. You're altering the standard that was set, which alters other things that you no longer have definitive information for. Most of Suzuki's maintenance intervals are preventative, but still. You're changing the baselines of which those intervals are measured.
Even beyond engine, in my line of work performance increases have side affects also. I'm in telecommunications, and LTE increased speeds beyond belief, but still doesn't do certain things as well as 3G which is why it's still used.
The placebo effect (and keeping up with the Jones') is strong in MX.
I don't disagree with your first and last sentences though.
It costs Suzuki nothing to produce a pipe of different dimensions or an ECU with different curves.
Suzuki know a thing or two about both.
As mentioned; the most legitimate reason to change is to change the power. EG sacrifice low rpm power for more top end.
Suspension is a different matter. Even suspension which is perfect for one person, can be terrible for another.
I had the Vortex x10 in my 2011 CRF450. The adjustability was nice, but I didn't really notice much of a difference in regards to hp gains... just a little more umpf in certain areas of the power curve in respective maps. That's just due to more fuel and different ignition timing. Unless you start modifying the internals you're probably safe in terms of reliability.
Pit Row
The stock pipe was very quiet, and fitted with a catalytic converter.
The stock airbox was designed to keep dirt out to allow Adventure Riders ride for weeks (months?) without cleaning the filter.
It was very lean stock to comply with European pollution rules.
Now it's offensively loud, with a K&N filter straight on the throttle body and a performance tune on the power commander. 80 RWHP!
MX bikes don't suffer from these compromises. Gains, without corresponding losses, are difficult.
2. Full FMF Ti system
3. Vp U4.4
4. Remap stock ignition.
Know that since you are on a RMZ your starting out behind the field. Not trying to start shit just being factual. Fuel and Exhaust should get you 3 HP.
