Touring Slip-on Ranking!!

For those of you that deal with slip-ons a lot (resale or dyno operator), or if you own one of these and have heard another slip-on, how would you rank them for loudness? Preferably with a dual setup (seeing that going from stock headers to Dresser Duals increased the noise of my SE IIs a good bit) rate these slip-ons from the quietest to the loudest (i.e 1, 4, 5, 3, 2…..) Please rank them based on your experience even if it involves a couple of these slip-ons.

1. Screamin' Eagle II
2. Vance and Hines Oval Slip-ons
3. Bub Dresser Dogs
4. Cobra 4” slip-ons
5. Hooker tuned flow mufflers
6. Kerker Slip-ons
7. Python 3 ½” Slip-ons
8. Samson Silver Bullets
9. D&D 3 ½” Big Boss Slip-ons
10. Khrome Werks HP+

Additionally, if you have the knowledge or experience with various slip-ons, rank them for performance or how they felt to you. To be able to look at these results later on rank them as follows:

Sound: 1,10, 5, 4, 2, 3, 6, 8, 7, 9
Power: 9, 5, 4 ,3, 2, 1, 8,10, 7, 6

Thanks!

P.S. The goal here isn't loud or quite for me....just a comparison of all the slip-ons (yes I know all the different slip-ons aren't listed, but these seem to be the most popular).

Update...

I'm looking for ranking against other slip-ons you have owned or listened to. This will make a great reference for people looking for slip-ons. I see these forums all the time with these questions..."I want louder or quieter"... the responses I see are "I installed X brand of slip-ons and they are a lot louder"...ok louder than what? So, if you have owned a couple of the above slip-ons, compare the two or three or whatever. If a buddy is using one and you are using a different one, how do they compare in Noise and Power to each other.

Overwhelming repsonse!! Part 1

Well since I didn't get the data I was looking for, I found a post from another forum that had a link to a a great comparison of 2-1 and 2-2 exhaust. The bike was a Night Train. It didn't list the partculars of the bike but I believe it had a 95" kit. All of these pipes were installed tested and dynoed.

So do you lose out with 2-2s?

A lot of people debate losing power with 2-2 pipes versus 2-1 pipes. The above results are a great examples of a broad range of pipes on one bike. Here are the averages....not really enough to debate about from what I can see.

2-2
Average HP: 92.3
Average TQ: 96.98

2-1
Average HP: 92.41
Average TQ: 98.1

I have a 95" in a night train. 510 S&S Cams. Home brew heads with a comp ratio of 9.5-1. S&S E Carb. Crane ignition, and a Rinehard 2-1 header. I run a plug gap of .060 and produce 102.36 RWHP. As a side note I still get about 38 MPG crusin at 75-80. I'm happy with it.

????stock stats???

Those were stats with stock "B" engines for HP?
they seem a bit high to me....Are ya sure the owners had done other performance enhancements other than pipes and Air cleaners?

Probably 95" engines with some sort of cam.

Linked article

The link I had found in another forum was to Part 5 of the American Thunder Night Train build. Part 4 was installing several 2-2 pipes and part 5 covered 2-1 pipes. It didn't mention what they had done in parts 1, 2 and 3. It was also done a while ago through SpeedVision.com, which is now Speed TV, and I haven't been able to find the other articles. So this could be an 98 or 99 EVO version or a 2000 - 2005 TC88 version.

Ok it's 15 minutes or so since this post. The bike was a 2000 Night Train. It's amazing what you can find with a good search engine (altavista.com). Here is a link to the entire article with the 1st 4 of 5 parts: American Thunder Night Train Build Parts 1-4

Here is a link to a better version of part 5: Word Document version of Part 5
