My muffler came with a tip configuration I have not seen before, (I have had several, most recently for my 400EX-traded for my Predator). It has 8 discs but instead of an endcap, it has an oval opening with about a 1.5 inch pipe mounted inside with a cone which has multiple perforations around it. I am used to a flat end cap. Has anybody seen this tip? Did it come from Polaris this way or did the dealer do this? They claim that that is the way it came to them. Any imput appreciated. This configuration looks to be a little more free flowing than a flat end cap but it doesn't sound as good. What tip configuration did everone else get?
