B&B Dyno results
I'm not about to type this list of results or just those of the B&B system since I would be here all night. They start at 2000rpm and go up to 7000rpm in increments of 250rpm giving Torgue & HP at each increment. E-mail Mark fowler at B&B and he will send you a copy or fax it:

There has also been some questions in regard to cutting out a plate on the B&B tips for more HP. This no longer applies to the now new & improved system. See my Question to Mark and his reply below: Hope this helps answer your questions
Bob-
The part you are talking about is a tip back. Why some people call
them
restrictor plates I do not really know. Even the new systems built
today
have tip backs on them however the opening is larger than it was
originally.
One thing to take into consideration that the inlet of the muffler is
3"
along with the pass tube. Then with the two outlets you have a surface
area
of over 5" coming out of the muffler. One of the purposes of the tip
back is
to help maintain the surface area from getting to big and loosing
pressure
not allowing the muffler to work properly. There have been some people
that
have spent a great deal of time to go in and opened these plates larger
with
a die grinder. The results of doing this will be a increase in sound
both
inside and out with little to no increase in power. To answer your
question,
yes you do have the latest design. It is up to you as to if you want to
spend the time to go in and open them up larger. I hope that I have
shed
some light on the matter for you and please let me know if you have any
additional questions.

Hello Mark-
<snip>
Anyway, I specifically asked the salesperson to have the restrictor
plates removed by the fabricators which I have heard so much talk about
doing yourself on the various ZR1 Net sites. He told me that the new
systems already have them removed due to customer input.
The problem I have is the continued talk about removing these
restrictor
plates. I have seen pictures people place on the web which as far as I
can see look similiar to mine and they have the plates.
Is there any way with the above information that you can verify that my
system is restrictor plate free? If I measure from the outer tip to
the
first rectangular opening it is 4.5" then futher in to the next
plate(which seems to vertically cut the opening roughly in half)it is
10.5". Is it this 1st and or 2nd plate which is the one being cut out
and which my system also has? It seems to me my system has the
restrictor plate.
I would greatly appreciate your comments, I would just like to know
