I have a new 2009 Razor and I want to add exhaust(slip on or full) and I also want to get rid of whatever shuts it down at 55mph. Obviously I don't know much about it so would someone please give me some tested and proven options.

Thanks.

slip on is a waste of cash. the best exhuast systems for the raptor are monsters, barker and, new dmc exhaust (not the old one). all come very very close in hp # so its pretty much whatever one u like the best. i decided on monsters myself. all of these systems are duals exhaust systems. u will also need a efi unit. i highly recomend the power commander 3. it will be the only efi unit u will ever need. there are some cheaper efi unit but they are not very good at all.
