BRRRRAAPPP!
Open up your bike and let it breath! This is my first 4.1 and Im impressed. Very well made and sounds great. Best part is the power gain. Do note that if you putting this on an EXC then you will need some sore of EFI tuner or race ECU to richen up the engine. I changed out the stock graphics for the KTM graphics.
Pros: performance|lighter|fit & finish
Cons: cost (maybe)

Every thing I wanted
Put on a 500excf thing sounds deep watched tons of YouTube videos that dont do it justice. 100% satisfied matched it up with a jd tuner and a smog delete feels like what it shouldve been for 10grand from the factory

FMF Factory 4.1 slip on muffler
I bought this muffler initially as a slip on for my stock header and then down the line purchased the titanium megabomb header for it. The muffler weighs about a pound less than stock and looks really good has a little more poppy sound as well. Once paired with the megabomb header there were noticeable power gains.
Pros: looks good|sound|weight
Cons: price
