My 2006, 660 Rhino exhaust rusted & both sides of the pipes fell (broke) off. I now need to replace with another one and will probably go aftermarket as the prices seem to be similar to a new "Stock" system. Unfortuneatly I need the entire system, not just the muffler & slip on pipes. I don't want loud, but a nice deep throaty sound would be nice. Performance is apprecaited, price needs to be low. Question - Which is the best bang for the buck and will last longer than 2-3 years (like my stock one) FYI, I took the fan off the engine so the exhaust runs alot hotter than normal... (this may be the reason why my stock exhaust did not last long??? Has anyone else had this problem or heard of it happening?) Anyways, I installed a clutch kit, a jet kit and a k&N filter a while ago... so any aftermarket exhaust should work fine.... Just need your help on which one to buy. My dealer wants to sell me a FMF Powercore 4 with stock header pipes.... Is this a concern (going with stock header pipes and an aftermarket pipe) or should I go with an entire system? Please help as I will be spending about $600.00 (Canadian) on the powercore 4 system, but would consider a little more if its worth it for something else.... Thank you....
