excactly what baggerboy says nice deep sound only loud when you hit it. I wont be changing it ever....2013 roadglide ultraI've got a V&H Pro Pipe on my 09 SG and I love it! Great deep sound and not to loud when cruising, but has a nice roar when you get on the gas.
Ok so I went in to buy the ProPipe today. When I pulled in to the Dealership a guy pulls up with a Thunderheader on his RG 103. And well I ended up getting a Thunderhaeder lol. Sorry to waist your time askng about the propipe. I had already seen some good reviews on the Thunderheader and the sound is awsome. We will see if I like it. God I hope it helps my low end a little.
