Cobra Slip on's?
 

When I bought my 12 RKC I liked the prior Screeming Eagle slip on's I had on my other bikes. So I had them installed before I took delivery. They are not very loud at all...in fact I bet are similar to the stock pipes.
I'm thinking about changing them out to the Cobra Oval 4" slip on pipes...
Opinions please??
I don't feel like blowing 400 or so on pipes if they aren't goimg be be a little louder, or look odd either....

Its the catalytic packed inside the header. It wont matter what you put in it, as long as the catalyst is in there, its going to be tame so don't spend anymore money until you address it. Many, inc myself have removed it. By doing so, it actually makes stock pipes sound like a slipon.
