I am dragracing my trailblazer in a couple of weeks and need to know if the green aaen spring will help? It is stock except for a K&N air filter and a DG exhaust system. I have run it twice before once without the DG exhaust and that time I run 41MPH. then the next time I run I put the DG exhaust on and it slowed me down and I only ran 37MPH. WIll this spring help?

 

It may actually be the exhaust system itself. DG is one of the worst for the polaris 2 strokes. Some people on here had them and claimed to have actaully lost horsepower!. But yes, when you pipe it you need to change the clutching to match the powerband of the pipe. That is why it is best to get a pipe and clutch kit from the same company cuz they are designed to work together.
