Nope, stock 09 so no cat but that's it. planning on adding the fuel moto head pipe and stage 1. Was going to do it all at the same time but the Pipes came off CL so I had to jump on them. I didn't have the disciPline to have them sitting in the garage waiting for me to gather funds to do the rest of the stage 1 so I had to mount them!

 

Been thinking bout some 4" jackpots myself and would be curious to see how they perform to my V&H monster rounds ( unwrapped baffles).
The " dyno tuned " aspect of their design is interesting, wonder if other manufactures go to that extent when producing their mufflers?

 

I am going to be selling my 3.5's.
They just dont have that deep tone and rumble I like. Blatty and tinny sounding.

 

I use the 'race' core on mine (4"), sometimes thinkin' they're a bit loud...
Horn is no use.
Love them.
