Hogzhaust to exhaust comparo thread!

So I was thinking there are alot of questions about CBEs and how they sound, loudness, drone, rasp, etc. but its hard to get a feel without a constant. I've tried to listen to youtube vids but the sound quality isn't good and I was thinking there has to be another way.

Boom Hogzhaust! Its cheep, easy, and lots of folks have done it (me included). Its a perfect comparo! So I'm gonna drop this here for people to use, I think it has the potential to be a good tool.

Here is my need: I like the volume of the Hogzhaust so when I do my ehaust I would like to stay around that level of volume. Any suggestions? Obviously I like the OBX due to price, and the Invidia quad tip for its look, but how do they compare as far as volume goes?
