Well, the Borla like many of the others is a cat-back, so I wouldn't really consider it a racing exhaust. If I were racing (off road use only) I'd be looking at doing header pipes, no catalytic converters, and probably two mufflers -one on each side. Also, there usually is a minimum length specified for the exhaust pipe, but it would be pretty short-- exiting in front of the real wheel. Look at some websites that feature NASCAR trucks, you may find a photo or two of what they run-- it's pretty aggressive I'm sure!

If you meant strictly from the muffler design, the borla muffler itself has a single inlet and dual outlet-- you can see right through it. Kinda like the old "Cherry Bomb" mufflers. See:



Hope this helps!
