Ya, mine sounds the same, its relatively quiet but has that deep roar when goosed

 

well actually mine isn't quiet at all... is your engine built?

 

Oh yes, I thought I mentioned this all ready but here it is:



Andrews 54H Cams
95" cyliders
KB forged pistons
Heads ported and milled to 75cc by Big Boyz
.030 Cometic MLS HG-10.25:1 static, 9.3:1 corrected
150lb , high lift valve springs
51mm HPI Thottle body w/170 intake manifold
V&H Pro Pipe HO < (new one)
HD race tuner kit
SE Clutch kit
SE heavy breather kit

 

I just don't understand why it's quiet then... mine is loud as hell

 

Well considering I had a V+H older pro pipe that had no fiber packing it was obnoxiously loud compared to the HO pipe. The HO pipe, believe it or not, was developed to be quiet at idle to adapt to the EPA regulations. As a matter of fact, I had no problem getting an inspection sticker with the HO pipe. Before I had to stuff packing in my old standard pro pipe to get my sticker. Plus I can hear my radio now!

Now before I stick my foot in my mouth, I still haven't dyno tuned my build yet and I'm still running on the break in download. I am sure that the sound level will change after the tune as its running on the lean side now.

 

You are right, the pro pipe is pretty loud to compare to. I love how the ho sounds, turns a lot of heads! Great performance pipe too, she really screams when ya get on her.
