Dual Exhaust for Terra crusher

[Monster19]

Hey

I found a Dual exhaust for a Terra crusher on E-bay i don't know much about these except someone said they aren't good
can you guys give me some input on it . The guy says it makes the Terra-crusher perform better

I don't see how they could add more power, they add another 10 in. of piping after the engine and its in no way tuned, that would diminish performance, not add. I think there for looks and that's about it. Personally I wouldn't bother with it.

Thank you Judgement, I appreciate the input :)
It makes my decision much easier.

its stated to give better performance, but its just not tunned and it make engine run leaner
