Hey guys, I was thinking of trying an end cap instead of my slip on. Has any one tried the end cap that on dunes sells? I was just curious how it stacks up to Mr. Hp's and others...Thanks in advance

 

I have not done a comparision but mine was a big difference from stock. I got mine off of ebay for $40 delivered. I think they are like $52 and he sends a 175 Mikuni jet with it. I have installed them on 2 other bikes with matching results.
