I am currently running the HPR endcap on the stock exhaust, I am thinking of getting the HPR topgun slipon when they become available, not sure to get the discs or the open endcap ? Any one tried both? We dont have sound test over here so that will not be an issue.

I love mine with the discs, from the seat of the pants felt same bottom end with more mid range and top end then the end cap.

 

I've got the top gun slipon with disk end cap & love it. The sound is deeper & not as loud. The performance is better than the end cap. The only problem I see with it, is it won't work with the cargo type six pack racks. It will work with the standard six pack rack tho.
