Up until
now, I have refrained from writing about or even entertaining
the idea of doing an article on exhaust systems. I
had been very satisfied with my existing system and
was very happy with both its performance and its deep
throaty sound. It may sound very conceited to even
suggest this, but I felt I had one of the more higher
performing exhaust systems and there was no need to
talk about anyone else's. There just was no need to
even consider it since exhaust systems can be very
subjective and even a personal experience. That was
until now.
At Dragbike.com,
we decided that it was time to explore other types
of straight-line racing and it was up to me to take
the reins and venture into Land Speed Record racing.
This is a sport where you start from a dead stop and
take off like a banshee to the 1-mile marker. It wasn't
how quick you could go, but rather how fast you could
go. That meant a hellatious amount of horsepower in
the higher RPM bands to be able to pull the very long-winded
gears capable of over 200+ MPH speeds. So it came
to pass that the Dragbike.com Trilogy Hayabusa was
given the challenge.
This meant that the Maximum Performance built 1397cc
motor would need re-tuning to meet the challenge if
it were to go to the E.C.T.A. Land Speed Trials at
Maxton, N.C. and attempt to pull 200+ MPH runs in
just 1 mile. My cousin Mike Caputo, owner of Maximum
Performance Cycles in Toledo, OH, and my personal
engine builder decided we needed to install an exhaust
system that would be in harmony with his motor. I
told Mike I had already decided to keep my existing
exhaust system. What did a couple of HP mean in the
grand scheme of things anyway? He raised his eyebrow
like Mr. Spock and explained to me that in order to
squeeze the maximum out of every bit of energy available
from my motor, I had to allow the motor to breath
properly at the high RPMs. I tried to explain to him
that my existing exhaust system sounded great and
that I was very pleased with its performance. I could
now see that he was giving me the evil eye and said,
"don't ask for my advice if you're not prepared
to follow it cuz." "Okay, okaaay, what do
you
 suggest
oh Sultan of High Compression?" He pointed to
his personal bike, a 99' Busa (evil twin brother to
my 01') and said "Akropovic." I laughed
because my current pipe was just as good a pipe as
the Akro in my eyes. I said to Mike, "If I'm
going to change my exhaust system, it had to be for
substantial horse power gains and not just for sound
and sparkle." So he looks intently at me at says,
"Well, if you really want one of the best, you
had better give a call to Brock Davidson." I'm
thinking, what could Brock Davidson do for my Hayabusa
that I couldn't? Wasn't he the person that had the
first 7-second Suzuki Bandit? So, Mike digs into his
Rolodex and gives me his number.
I had already installed his BDE Clutch Cushion Kit™
and was very pleased with its performance at the track.
What did I have to lose? After about an hour of conversation
with Brock as to my objectives for the Dragbike.com
Hayabusa, he decided that I didn't need a "Brock
exhaust pipe" at all, but rather the Brock Davidson
Enterprises Street Smart™ Series Exhaust System.
I just rolled my eyes and said, "What the hell
was the difference?" He spent another hour explaining
to my feeble brain that one was a great exhaust pipe
capable of out pulling any other pipe on the market
by quite a few horses and the other was a complete
Brock Davidson Street Smart™ Series System technology.
Brock says that "any manufacturer can sell you
an exhaust pipe. We provide you with the best pipe
we know how to make, which is specifically designed
for those who drag race their street bikes, AND show
you how to use it." We set up a date to take
the DB.com Trilogy Hayabusa to Dayton, OH, for a complete
Dyno tuning session and Brock's personal tuning adjustments.
I had only
agreed to this session because of my cousin Mike's
suggestion that I could get some serious HP out of
this system. Therefore, I asked Brock once we had
strapped the Busa on the American Made Cycle Model
250 DynoJet Dyno to first tune my existing pipe to
its maximum efficiency. He agreed, so after 4 pulls
on the Dyno we were able to muster 187.9 HP SAE out
of my favorite sounding and most awesome looking
Stainless and Titanium pipe. Now before some of you
start criticizing the numbers and saying I should have
gotten more, let me just say that even I was prepared
to see higher numbers myself. However, the map I was
using was tuned using a sniffer (for proper air/fuel
mixture) on a Dyno jet 250 and it was as good as it
was going to get with the motor combination and pump
fuel (Sunoco 94) I was using. I personally oversaw
all adjustments to the map and watched each pull on
the Dyno get better and better each time. There was
no sabotage on Brock's part because he had no need
to do so in his mind. He felt his system was far superior
in every sense of the word and I thought he was just
conceited. What if I used a different
map? Maybe I could have gotten more HP and maybe I
couldn't, but for this day and time, this map, this
is how it was. End of subject.
Off came my current exhaust and on went the
new Brock Davidson Enterprises Street Smart Series™
Exhaust System in Titanium and Stainless. Brock then
installed a BDE 1397 baseline map personally developed
by himself and one that he uses in every 1397cc motor, into my
Dyno Jet Power Commander II. We then made another
pull and what do you know? 193.3 HP SAE. I can
tell you I was just tickled to see those kinds of
numbers and was ready to pull the bike off the Dyno
when Brock stopped me. He said he was ready to begin
applying the Street Smart(TM) Series system and to
stand back. Stand back? Stand back for what?
Brock
then started applying his System technology to the
Dragbike.com Trilogy Hayabusa and would then make
another Dyno pull. Again, 2 more HP, then he did something
else and does another pull. Another 1.2 HP, then he
did something again, and again, and again and he didn't
stop doing this until he had achieved 201.5 HP SAE
to my baby after over 15 Dyno pulls. He had gone from
gaining just 5.4 HP by changing to his exhaust system,
to gaining an additional 8.2 HP by applying his Street
Smart(TM) Series technology to his already superior
exhaust pipe. Oh wondrous god of increasing ponies!
I wouldn't have believed it if I hadn't seen it with
my own eyes. A total of 13.6 HP SAE over my favorite
exhaust pipe on the market. This just couldn't be
I thought, but there it was in black and white. But
I now understood what Brock had meant by installing
just his exhaust over applying the entire BDE Street
Smart™ Series Exhaust System technology. Nevertheless,
how could this technology be shared and given to those
who could not bring their bikes to his facility in
Dayton, OH? He just smiled and told me that once you
owned a Street Smart™ Series Exhaust System,
you could enroll into the Street Smart™ owners
group and gain secret access to portions of his website
www.brockracing.com
that explains and shows in detail everything that
he had applied to the Dragbike.com Trilogy Busa. You
would also have access to him on the telephone to
help with any tuning concerns you may have which could
be very valuable. At this point I had renamed Brock
to "Master Yoda" and was now convinced that
I had struck a gold mine of wealth in technology that
would give me every ounce or power available I could
get out of my bike. Maxton, here I come. I was now
armed with the knowledge necessary for me to be able
to give my best shot at attaining speeds of 200+ MPH
while at Maxton.
If you have
ever wanted to get maximum horsepower for your big
horsepower motorcycle, whether you have turbo, nitrous
or just motor only, then I recommend you consider
the entire Brock Davidson Enterprises Street Smart™
Series Exhaust System by Hindle before you make your
next purchase. I couldn't be happier with my cousin's
advice (except when he told me tequila would make
my headache go away the morning after) thanks, Mike.

Davidson Enterprises Street Smart™ Series Exhaust
System by Hindle in ultra-light stainless is available
