Hi

I've got a 2008 Nightster currently with Cycle Shack slip-ons. They sound great. Just perfect as a matter of fact.

However, I don't like the cycle shack looks. But I love the look of V&H Big Radius 2 into 2 black: http://www.vanceandhines.com/product...ius22-blk.html

I live in an area with a noise restriction by-law and am wondering how much louder the V&H are compared to the cycle shack slip-ons. Does anyone know?

Also, is it possible to get after market baffles for these to quiet them down a bit if they are too loud?

Thanks for any help

I too had Cycle Shack slip-ons before i put the V&H big radius on. In my opinion they are very nearly the same with the stock baffles in. At first you may think the V&H are slightly louder but i believe that is because the Cycle Shacks are slash cut downward directing most of the sound down and to your rear, away from you, while the V&H are slash cut more to the side, allowing more of the sound to be heard by the rider.

 

mine supposedly put out 114 db. MA has a legal limit of 97 db. im going to look into some quiet baffles

 

I have them on my nightster and they are pretty damn loud, they are not much if any quieter than the short shots. I looked at and listened to a lot of different exhaust systems before I bought the big radius, they had the best of both worlds in looks and sound of everything I looked at.

 

Wow, if they sound like the cycle shacks then that's great. I thought they would be much louder.

Just in case they are too loud for my neighborhood, does anyone know if after market baffles are available for the Big Radius. Where's a good place to check?

Thanks again,

They do come with baffles installed. I took mine out, people seem to complain riding behind me....rock on!

 

Funny, I was thinking of putting in quieter baffles.

A few questions:

1. Don't you need the baffles to get some back pressure?
2. Did you have to do a remap when you took the baffles out?
3. Can anyone recommend a Fuelpack for the Big Radius? V&H recommend their own, but I don't know if others would also work.

Thanks again,

It's going to come down to what you want to do with your bike. Fuelpak is good for the OTS tunes that V&H has and it's built with leniency in the curve. The more precise tuning is going to get a little more pricey one for the unit, like a PC V, and two for the time it takes a tuner to dyno/tune the ECU.

If all you're doing is adding components that V&H have tunes for, I would go strictly for the Fuelpak and maybe a x14ied for the closed loop driving.

 

Never heard a set on a Sporty, but my buddy has them on his 2008 Rocker C and they are loud with the baffles in. I have the baffles out of my Martin Bros pipes and they get loud when you get on it and the back idle is just awesome sounding.
