M620ie Termignoni exhaust shooting..

[mr.freezer]

Hi guys... today I mounted termignoni exhaust on my monster 620ie... sounds great, but when I'm not pulling gas and deccelating it is shooting... guy who was riding behind me said that he saw flames too... I'm afraid if this does not damage my engine... a  like the sound, but if it will damage my engine I would mount stock exhausts back... thanks..

You must reset the trim, unless you have a CO analyzer, you will need to take it to a shop for this; did you also installed a performance air filter?

when you hear the BANG do you loose a bit of power too? check the coils, front and back, screw them tight, not the coils BUT the coil CABLES...

I do not lost power... I di not mount anything else just exhaust... I know thath it should be exhaust, airfilter and ECU... but it costs so much...

I have termis,  pods and ecu, but ecu was designed for airbox, man, changed it and it's a beast, don't know if I am lucky but baby feels more powerful than ever, guessed Darkmonster620 advice is your way to go if you are not loosing power

You may have an exhaust leak.  Check all the connections and make sure they are tight and leak free.
