Okay I'll bite! I'm about to put them on. How does the sound change? I was looking at putting on the double groove ones.

Anybody running RUSH exhaust with a true dual set up? If so, what header pipe are you using? Any pro's and con's with the RUSH exhaust?
I'm still debating between the Vance & Hines Ovals or the RUSH. Definately will go with a true dual set up, sert and dyno tune. Do you notice a significant amount of torque loss using the true dual?

 

havent gotten to pics yet but i love my d&d fat cats.bike runs a lot better and the engine seems smoother too.i am more interested in perfoemance than looks. i mean how much can you see @ hwy speeds?if i dont get back in the mtns soon,they will have to lock me up in a padded cell.deals gap......next project is installing camcorder w/remote camera & mike.rw

 

They will make the bike louder or quiet and also change the tone of the pipes. See if you can go to a dealer and find a set with the double grooves and listen before purchasing. I was gonna go the exact same route you are UNTIL I heard them compared to the 1 piece and thought the double grooves sounded like crap(They give off a shushing sound). Luckily the Tech told me about this before buying and the fact that they had a bike with them installed already for me to listen.
