Buell Exhaust Comparison, Hawk vs. EBR
I switched out the Hawk Exhaust on my
Buell XB12R with an Erik Buell Racing Exhaust. Here's how they stack up.
Both units use all of the stock mounting points, though the Hawk unit keeps
the Exhaust valve servo mount. The EBR
unit has a deeper, smoother sound, which makes it seem quieter. The Hawk
muffler has a sharper tone and will set off car alarms (@2:03). Both pop
regularly off-throttle. On the stock ECM with a K&N the EBR feels much more
torquey and smooth down low. With the right tune I suspect that the Hawk
would make more power on the top end.

Here's my -98 Buell S1 Lightning on a mobile Dyno. A famous finnish drag
racer Tuoppi is pulling a 110 rear wheel horsepower pass. That
combined with over 130 Nm (95 ft.lbs) of torque makes this a hell of a bike
