As far as I can tell this exhaust/muffler is what I have on my dub.
They have the baffles removed, guy cut the ends off, removed the
baffles, welded the ends back on. Very nice sound and mount to the
stock headers no issues. Personally I want a set of fishpipes, as I
love the older look. BUT, I love the sound and looks of mine...so it
is a toss up.

So 54 PS is actually 53 bhp. I got a brief peak of 52 BHP on the
dyno but
that figure is well within the tolerances of different dynometers.
The dyno
I used was considered to be conservative according to various
people who had
been on other dyno's before using 'mine' so I think my figure of 51
with a
52 'bump' was close.
If the cams are good for it, the bike might possibly make another
HP or two
above 7400 rpm, which is where my pipes make their maximum on the
W, and the
Dunstall Decibel was after all designed to allow the Triumph twin
to make
power up to 8500...But it would only do that if the motor was
modified with
cams and head work to do that. I don't know if the 7500rpm point on
the W is
dictated by my pipes or the motor but I think at least one person
on this
site dyno'd a Dunstall equipped bike and got...50 bhp...So one
would assume
the motor does 50 bhp. Obviously there will be slight differences
in motors
and measuring equipment and a properly bedded-in motor on an
optimistic dyno
could easily see 54 bhp or PS but on balance 50 bhp is about right.

Am I missing something here, you said that 50bhp is the roughly the
most you can get but the aftermarket site in Germany says you
can get
54ps, with some of their Silverstone exhausts, isn't 54ps the
same as
54bhp?
