Buckeye go back and look at the graphs again, On Dales Quad, the HPR19 just at 5500 rpm was making 10 hp more than the V1, and 4-5 hp more than the V2 across the curve, it was peak hp where they were 2 hp apart, those test set fire to my azz to get the DCS-5 to get close to those numbers.
HPR19 is a work of art, you have to understand metal fabrication to appreciate the craftsmanship and detail on this exhaust system, In the beginning back in 2010 I used to say the same thing $1000 for a pipe, and was leery due to the testing back then seemed very biased against Q , but seeing the the graphs on a ATV Dyno its all about respect to Mr Hall, the V2 will be hitting $900 I hear when the next batch comes out, When you really think about it the pipe is the most major item the LT500 needs  other than porting.
