I like the standard Sport Jett .50 myself.
the Fire is (Front Intake, Rear Exhaust) and really set up for a tuned pipe.
The BSE is a Bar Stock Engine, very nice looking, but minimal performance gain over the sport jett (don't hammer me too bad for that Bob, and correct me if I'm wrong).

Yep, thats about right
Internally, the engines are about the same.
The bar stock engines do have a very slight performance improvement... but most people do not notice it.
The BSE engines are just real works of art. Cost a little more to produce, and the resulting engine price is about $50 more.
The FIRE engines can be more powerful, in that they are more custom tuned for the application when the pipe is setup.
What is your application Strykaas ?? That can help with selection.
