I was just reading about the new Double Barrel power exhaust that Duncan had just put out. Does anyone know how good that is. Could it be better than the big gun exhaust? How much extra horsepower will the Duncan exhaust give me?

 

The Duncan or basicly identical DMC full exhausts put out great power from top to bottom. On a 100% stock 400 the power difference was almost amazing-no question about it. That's the good news. The bad news is it's **LOUD**REAL LOUD! It is easily the loudest machine I have ever heard-even when compared to machines with damaged exhausts.
