[Sxr-MIKE-420]

I have $1500 and I want to upgrade my 2008 SXR-800. I want it to be powerful enough for backflips and barrel rolls. I want it to be more powerful yet not lose any reliability. I was looking at the factory wet pipe and maybe the tbm superpump cone. I also want a new ride plate and intake grate. Any suggestions on brands or different setups?

Like I said I have around $1500 and I want to start flipping it and getting mad air this summer. Any professional ideas and help is appreciated!!!
