Hey Schoona
Does that termi slippon kit for $1400 come with an ecu and air filter to suit??
Not sure on the newer models,
but usualy if you play with the exhaust ,the ecu needs to be changed or tuned/power commander to suit?
Can't recomend a good system for your model monster,but those competition werke's jobbys, look real good ,and for $764 from monster parts plus post
Probably worth getting the baffles for the extra $70 just in case ?
And again you might need to change the ecu or add a power commander? and have it retuned
