Is it a risk to put on aftermarket pipes without a tune?

If I were you I would move to Texas or a less extremist state than California...

Well hey, at least I can get internet p*rn in California, unlike Texas!

We get all the bike p0rn we want. What ya talking about?

Thanks for all the input. I did call the service advisor at my dealer and besides warning that it is "possible" that adding an aftermarket exhaust could void my warranty he would recommend that the bike be tuned after removal of the catalytic converter and addition of an aftermarket slipon exhaust. Of course given that I live in CA, no dealer is legally able to modify the tuning, so getting it professionally tuned does not seem possible. After looking through the threads it doesn't appear that there is any DIY way to tune the new Storm ECUs, with Tune ECU for instance. Is that correct?

BT Moto does have an ECU flash available for the 2025 rocket 3. I used them for my R1 after decat and 3/4 exhaust install and it worked amazingly. Only thing is it may be a stock system tune rather than a cat deleted one.

From my sources the 2.5l Storm ECU has not been cracked ... as yet.

There is a certain tolerance on the tuning, but it will never be 100% correct with out re-mapping.

I have the 2025 GT Storm and would like the exhaust note to be more noticeable so cars know when I'm around. Currently I don't believe there is an aftermarket exhaust available on the 2025 because of the dual O2 sensors, but when I contacted Competition Werkes they said they are working on making one available. I do worry, however that without a tune the cat delete and aftermarket pipes could end up damaging the engine, by making it run too lean for instance. I ride a lot, 12K miles a year and justified this purchase based on what seems to be great longevity of this bike, compared to my previous bike (a Ducati) that became a chronic problem after about 60k miles. What say you?

Speak to Paul Bryant on here. His new 3:1 system can be ordered with whatever O2 sensor plugs you require. The ECU will then self-learn the correct fueling. But it would be better to have a remap.

The OEM setup is intentionally lean. The ECU can adapt to changes to parameters up to a limit to maintain exhaust gas measurements. Once you're outside the limit of adaptation the ECU can't go any further and a remap is required to optimize the fuel/air stoichiometry. If the backpressure of slip-ons or exhaust changes are within the tolerance of the ECU limits, then bolt it on and have fun. If not, then a dyno tuning session would be in order.

As has been pointed out in this thread, any changes to intake or exhaust would obviously benefit from a remap. Not to mention the fact that even the Storm addition, according to a salesman at Triumph, is still restricted. So remapping will not only ensure the engine runs properly, but will also free a lot more horses - win, win!

You can gain a bunch of ponies by the stock mapping just resetting the throttle limits: One note, if you reflash the ECU to reset the throttle valve settings, you'll also reset the adaptations. That action disables your cruise control until you do the switch check (i.e. after flash, actuate front brake, rear brake, turn throttle all the way off, actuate set and resume switchs and then the cruise should work. You can verify that by ensuring DTC 1575 is clear in TuneECU).
